Mit RGB zu Bitcoin-basierter Tokenisierung – Im Gespräch ...

with the recent rgb smart contracts news above lightning is there a 'possibility' to smart contract with yourself to cold storage in lightning form?

i mean with the 'possibility' to cold storage for like 20 yrs or something 'safely'
https://rgb-org.github.io/
its says:
RGB uses blockchain as a state commitment layer and Bitcoin script as an ownership control system; while smart contract evolution is defined by off-chain schema and Turing-complete scripting system using Simplicity language
and
As a security mechanism RGB uses single-use seals defined over bitcoin transaction outputs, which provides ability for any party having smart contract state history to verify it’s uniquiness. In other words, RGB leverages Bitcoin script for its security model and definition of the ownership and access rights.
and
Each RGB smart contract is represented by some genesis state, created by smart contract issuer (or, put simply, issuer) and a directed acyclic graph (DAG) of state transitions kept in form of client-validated data (i.e. this data is not stored on blockchain or within LN transactions/channel state). The state is assigned to unspent bitcoin transaction outputs, which defines them as single-use seals. The party that is able to spend corresponding transaction output is named a party owning state: it is a party that has the right to change the corresponding part of the smart contract state by creating a new state transition and committing to it in a transaction spending the output containing previous state. This procedure represents closing of a seal over state transition, and a pair of spending transaction and corresponding extra-transaction data on the state transition are named witness.

Instant is infinitely faster

Bitfinex customers will be able to use bitcoin in their account wallet to instantly shop from Bitrefill’s international catalog of digital gift cards and mobile phone refills for 170 countries.
Bitfinex recently introduced support for bitcoin deposits and withdrawals on the Lightning Network. With newly added Lightning deposit and withdrawal features at Bitfinex, customers can spend less time waiting and more time trading… or shopping!
The provision of this new payment feature underlines our companies’ commitment to building a new digital economy, Bitfinex and Bitrefill utilize customized versions of Lightning to open large channels together, exceeding the default limits in place, but allowing better flow and reliability to users.

Lightning-powered initiative

Bitrefill and Bitfinex have created the world’s first dynamic B2B settlement process over the Lightning Network.
In the background, Bitrefill and Bitfinex will instantly settle payments automatically over Lightning, using a dedicated channel setup, eliminating the need for B2B credit-term relationships.
“We believe that getting bitcoin exchanges on to the Lightning Network early is integral to preparing for the next wave of adoption and building out a parallel economy for Bitcoin. This collaboration signals a new era for Bitcoin commerce.
We will continue to work closely with Bitfinex and other businesses to develop Lightning solutions and products that make living on crypto a reality, eventually removing dependability on fiat rails”
— John Carvalho, CCO at Bitrefill

‘Closing the loop’ for Bitcoin’s circular economy

The joint initiative aims to ‘close the loop’ for Bitcoin’s circular economy by integrating Bitrefill’s catalog into the Bitfinex.com website, while leveraging the cutting-edge capabilities of the Lightning Network.
Earlier this year, Bitfinex and Bitrefill also created a consortium with other industry players exploring the development of open-source technology to enable token functionality on the Lightning Network, based on the RGB protocol.
“Bitcoin’s use as a means of payment represents an important milestone in the inevitable journey towards mass adoption. This is why the Lightning Network is so important.
As an exchange, Bitfinex is at the forefront of developing solutions utilizing this technology. This venture with Bitrefill further demonstrates our commitment to the crypto ecosystem and all the great work that is being done.”

Forward Thinking Friday - 9 October 2020 - Airdrops and Collateral

Forward Thinking Friday - 9 October 2020 - Airdrops and Collateral
Welcome to Forward Thinking Friday, a regular venue to discuss ideas, concepts and designs that push Decred further, bigger and better. Topics raised can be anything ranging from:
  • Technological improvements or enhancements
  • Unique opportunities well serviced by the Decred protocol
  • Responses to competing protocol designs and features
  • Integrations and Infrastructure
  • Marketing and Project Messaging
https://preview.redd.it/74cvfm7p26s51.png?width=929&format=png&auto=webp&s=907f5e4c7d96a67bafd906c0207efd82a84291be

Airdrops and Collateral

For this weeks focus topic, I am keen to explore two ideas and concepts and get stakeholder feedback, input and general thoughts. Personally, I think both of these are interesting methods to create new hype, interest and attention, and in the case of collateral, an essential path to monetisation and ultimate success.
Idea 1: A Second DCR Airdrop
My sense is that the market has reservations regarding the volume of DCR held by early investors, founding team and contractors. Irrespective of reality, this seems to be at least one adverse perspective. I would love to explore ideas/feasibility about hosting a second DCR airdrop.
Perhaps we deploy a portion of the treasury, perhaps via donations, perhaps it is a method to attract valuable contributors, developers, DEX liquidity etc. Perhaps we create a sidechain that locks a portion of DCR, issue an Ethereum ERC-20 token that is a right to claim and thus create unforgeable airdrops on another chain. Perhaps we create bounties via the RFP tool to deliver work within specifications. Pre-determined rewards for delivering some of the repeated desirable features from past FFF. This is a lso a path to attract new devs.
  • Coldcard Implementation
  • DCRPayserver
  • Ledger integration
  • Multi-sig functionality inside wallets
  • LN split tickets
  • A clever marketing campaign
  • RGB smart contract system
  • Drivechain/Sidechain implementation
Idea 2: DCR as pristine collateral
Chris Burniskie and Chris Dannen have both commented on this and I am also 100% in favour of creating systems that take DCR as collateral. A MakerDAO esque system, with some modifications that Ross Ulbicht actually has a great take on here, seems like an interesting approach. I have also considered what it would take to enable people to create their own on-chain treasuries/multi-sig wallets so as to create a form of on-chain business. How can we further create an internal circular economy inside Decred which has money, credit, treasuries etc. Decred is an incredible accounting system, lets explore how we take this further.
I will leave here a post by Raoul Pal from his GMI newsletter focusing on Bitcoin as pristine collateral. I don't know about you, but this is my long term end goal thesis for both BTC and DCR, as the ultimate pristine collateral.

Would this allow a someone with NO bitcoin to buy on bisq

As far as I understand BISQ requires a deposit as collateral to make bitcoin purchases.
Couldn't you develop some type of smart contract that allows a person who wants to buy bitcoins on BISQ, but has 0 bitcoin to use as collateral.
For example I could loan my bitcoin with the smart contract stipulation that I will be the equivalent of $20 dollars of btc after they've purchased, or something along those lines
Just a shower thought.
Could bitcoin not currently support this type of a transaction.
I know that lightning is getting something for smart contracts RGB but strike (if available to you )already makes it fairly easy to buy btc lighting instantly

hey i have some questions about cryptocurrencys

so i am really new to all that. and my english isnt the best so bare with me and help me understand all that better
the thing i do not understand is: what does satoshi do with all his coins (better what could he do)
and why are there so many transactions (3,500 says google) per block why not just one per block?
and then WHEN will it happen that bitcoin mining just isnt profitable anymore because of the to high electricity costs.
so i am in a funny position where i dont have to pay for my energy bill but all i have, is a crappy internet connection and a ryzen 5 8 gb ram laptop, (i am currently typing this in shool)
could i start mining or would i just be crushed by someone with 8 RTX 2080 ti super in a cool rgb rig in his climate controlled closet?

[USA-OH] [H] Desktop - i9 7920X, GTX 1080Ti, 64GB DDR4, 1TB SSD [W] Local Cash

Hi people, I have a computer that I built a few years back and would like to get rid of. This computer has never been used to play any games, mine bitcoin, etc. My brother used it as an office PC.
Okay so here is the full part list, along with what I could find each part for at the cheapest...
CPU: i9-7920X Skylake 2.9GHz 12-core - $600
GPU: GTX 1080TI (ROG-STRIX-GTX1080TI-011G-GAMING) - $600
Motherboard: ASUS TUF X299 Mark 1 - $350
Memory: Vengeance LPX 4x16GB 2666MHz DDR4 RAM - $220
Storage: Samsung 960 EVO 1TB M.2 - $200
AIO: Thermaltake FLOE RIING - $160
WiFi: Asus PCE-AC558T - $35
Case: CORSAIR CRYSTAL 570X RGB ATX CASE - $150
PSU: EVGA 850 G3 - $140
OS: W10 Pro
I'm asking for the combination of all these prices, and sell the whole computer as one (I don't want to part out right now). So $2455 for the rig. I'm not going to add in the cost of windows. If my prices are nuts please let me know.
Your sweet proof
I don't have a CPU-Z because I didn't know that was a requirement before I reset windows. I hope the UEFI picture makes up for it.

Bitcoin, future colonne vertébrale d’une révolution monétaire – Le protocole RGB, une renaissance ?

Bitcoin, future colonne vertébrale d’une révolution monétaire – Le protocole RGB, une renaissance ?
L’histoire des fameux jetons cryptographiques est une vraie montagne russe depuis que leur concept a été énoncé pour la première fois, quelque années seulement après l’invention du Bitcoin. Aujourd’hui, nous allons rapidement explorer ensemble le passé de la folie de l’émission de tokens sur Bitcoin, puis nous intéresser à son futur possible. C’est parti !

La genèse de jetons cryptographiques, les “Colored Coins”

Dès 2012, nombreux ont été les curieux à vouloir exploiter les propriétés de la blockchain du Bitcoin au-delà du simple pouvoir du transfert de la pièce native du protocole. Grâce à la structure des UTXO’s (Unspent Transaction Outputs) du Bitcoin, il est possible de distinguer des pièces individuelles en les marquants avec de l’information additionnelle.

https://preview.redd.it/zryam6n2wzp51.png?width=600&format=png&auto=webp&s=ae081f769e903d86ab5777c6f5196360a3572b70
Exemple d’émission de pièces colorées (Colored coins) sur Bitcoin
Le procédé en question se nomme “Colored Coins”, simplement car les données supplémentaires qui sont rajoutées dans une transaction pour marquer un UTXO Bitcoin particulier suivent le standard RGB (“Red, Green, Blue”). Ce standard est utilisé pour définir une couleur en chiffre.
Ce concept se heurta cependant à de nombreux problèmes de scalabilité et de programmabilité rapidement, bien qu’il fût prometteur au niveau de son ingéniosité permettant de se reposer sur une base protocolaire déjà établie et aussi sécuritaire qu’est celle du Bitcoin.
S’en suivit la création de nombreuses plateformes, telle que l’Ethereum, explicitement conçues pour une création facile de jetons cryptographiques.

Les fonctionnalités recherchées des jetons cryptographiques

De nombreuses raisons expliquent l’excitation et l’empressement des développeurs et investisseurs confondus au sujet des jetons cryptographiques.
La possibilité de procéder à des levées de fonds en cryptomonnaies ad-hoc, d’émettre des jetons adossés à des monnaies fiduciaires (stablecoins) ou encore des jetons non-fongibles représentants des biens purement numériques ne cesse de pousser notre imagination.

RGB, un retour aux sources

Bien qu’une majorité des efforts déployés pour la création d’une plateforme parfaite servant à l’émission de jetons se concentrent sur des réseaux hors Bitcoin, certains n’ont pas oublié l’ambition de réaliser celle-ci sur la première et principale crypto-monnaie.
Le protocole RGB est une de ces initiatives et un projet lancé et maintenu par des vétérans de l’industrie. Initialement conceptualisé par Giacomo Zucco et Peter Todd, RGB a avancé à grand pas une fois que la maintenance du projet a été entreprise par le Dr. Maxim Orlovsky et Pandora Core AG à la mi-2019.

https://preview.redd.it/6dod5ad4wzp51.png?width=324&format=png&auto=webp&s=6777c9838b79e3f75cf6f7233135f371ad2c939e
Le projet est maintenu selon une liste de standards publiée par l’association BP/LNP, qui rassemble un ensemble de propositions et de librairies de développement pour tous les projets ne touchant pas directement la première et deuxième couche du Bitcoin.
RGB est supporté également sous forme de financement par des firmes telles que Tether, Bitfinex et Bitrefill.

Le fonctionnement de RGB

Le protocole RGB se définie comme une troisième couche du Bitcoin, car elle utilise non seulement la première couche, mais peut également utiliser le Lightning Network pour son fonctionnement.
En tant que plateforme de contrats intelligents, le protocole RGB se distingue fortement de tous les projets antérieurs basés sur le Bitcoin et des plateformes hors Bitcoin.
Le protocole RGB se vante de pouvoir régler les problèmes suivants :
· L’inévitable goulot au niveau de la scalabilité d’une structure de donnée Blockchain qui rend difficile l’utilisation de jetons numériques à grande échelle.
· La confidentialité en défaut de la plupart des plateformes blockchains puisque l’ensemble des transactions et bien numériques conçus par-dessus celles-ci sont sujets à de l’analyse et surveillance.
· L’inefficience des contrats intelligents actuels, souvent dûe à des langages de programmation non-audités et à des problèmes de gouvernance des plateformes.
Pour ce faire, la création de jetons sur le protocole RGB se déroule selon une méthode particulière.
Premièrement, l’ensemble de la logique de contrat intelligent et de la création de jetons se fait hors de la première couche au travers de schémas inhérents au langage Simplicity. Ce langage permet la création de contrats complexes sécuritaires. Il faut voir cette étape comme la création des règles que les jetons devront suivre par la suite.
Tout récemment, la compagnie Blockstream a fait mention de ces avancements et a lancé le code source de Simplicity, qui sera bientôt disponible sur la plateforme Liquid, qui est une sidechain du Bitcoin.
Pour illustrer l’unicité d’un jeton digital particulier ainsi que sa possession, le protocole RGB fait usage de sceau cryptographique à usage unique (Single Use Seal), représentant l’état d’un contrat intelligent, qui est ensuite inséré dans un UTXO Bitcoin particulier. Les UTXO’s sont les monnaies distinctes sur le réseau Bitcoin et sont uniques, donc en liant un jeton ou un ensemble de jetons à un UTXO, on le rend clairement unique.
Par contre, tous traitements de l’état d’un contrat intelligent ou changement de possession d’un jeton se fait au niveau local par le détenteur des jetons ou du contrat intelligent en question. Le détenteur peut procéder à des changements de l’état du contrat intelligent au travers d’un état de transition et en dépensant l’UTXO contenant le sceau à usage unique.
Lorsque le prochain utilisateur reçoit les jetons, il doit valider le DAG (Directed Acyclic Graph) où sont marquées toutes les données de changement d’état du contrat et de changement de possession du jeton, en regardant s’il correspond bien aux règles définis par le contrat intelligent en Simplicity, aussi appelé Schéma.

Un exemple de graphe orienté acyclique, ou DAG (Wikipédia).
Il n’existe donc pas de blockchain dans RGB, seulement des nœuds qui permettent aux usagers de valider que les règles locales du jeton ou du contrat intelligent ont été respectées. Chaque transaction est alors un nœud (sommet) du graphe. L’avantage, par rapport à la structure en arbre des blockchains, est qu’il est beaucoup plus rapide de parcourir et de traiter les données. Le problème des plus courts chemins – trouver le chemin le plus court entre deux sommets – est ainsi résolu de façon linéaire.
Il existe évidemment les concepts de clés privées et de Script (le langage du réseau Bitcoin) pour prouver l’authenticité de la possession des actifs cryptographiques en question.
Finalement, RGB peut se jumeler au réseau Lightning grâce au protocole Spectrum de Pandora Core AG, afin de permettre une coordination par multiples parties sur le changement d’état et de possession sur des jetons ou des contrats intelligents RGB. Cela permettra aux usagers de créer des plateformes d’échanges décentralisées (DEX) par-dessus Lightning avec des jetons RGB !

Conclusion

L’internet ne s’est pas construit en une année, il a fallu plusieurs décennies pour compléter les plusieurs couches qui font maintenant partie du protocole TCP/IP. Certains sont prêt à faire le pari que le modèle de l’internet par couche se reproduira également sur le Bitcoin. L’équipe du protocole RBG sont déjà en train de construire la troisième couche alors que le Lightning Network, n’est pas encore finie. La plateforme de choix pour la création de bien numérique n’est pas encore garantie. Dans bien des cas, il y a plusieurs questions scientifiques auxquelles il faudra encore répondre. Mais en observant ce renouveau à retourner sur Bitcoin pour la création de bien numériques, c’est à se questionner si la réponse ne se trouvait pas droit devant nos yeux… depuis le tout début !

Finally done my first DIY PC build from scratch, although not my first PC. Past computers built by shops. Components, including *ones reused from my old build:
  • BeQuiet Base 500
  • AMD Ryzen 2700x
  • MSI B450 Mortar Motherboard
  • MasterCooler ML240L V2 RGB AIO
  • NAXN 650w PSU, non-modular. (Cable management with it is a nightmare.)
  • 2 x 8GB DDR4-3200 Sport Balistix
  • Galax GTX 1070 (2nd-hand too! Bought it from someone who used it for bitcoin mining.)
  • AverMedia Live Gamer HD 2 PCI-E Capture Card (Outer shell removed. Can you guess why?)
  • Fans (2 x SickleFlow 120mm RGB included with AIO, 1 x Silent Wings 3 140mm, 2 x Silent Wings 3 120mm)
  • IPS 1366 x 768 LCD screen, salvaged from my father's old laptop. Secondary monitor inside my case. ;-) Extra parts ordered from AliExpress: Controller board, acrylic case to house controller board, Molex-to-2.5mm Jacket plug, 19cm HDMI ribbon cable.
  • Last but not least, first-time installation of LED stripping to the case interior.

Granted, not the most epic of builds, but I am proud of it anyways because it is extremely functional, clean-looking (???), as economical as I can get it, and I am able to give a new lease of life to supposed 'broken' computer components.

29, building my first pc since I was teenager. Help?

Hey guys I’m 29, just started working again after Covid, saved you a pretty penny to build my first pc since I was like 13-14 years old. Ngl seems so much easier with websites like pc part picker.
I’m mostly going to be gaming on the lighter side of things, but I figured I would buy a step or two up so that if I decide to play something a little more heavy I won’t have to make many/any upgrades to play.
Don’t care about how it looks, currently my ram is rgb because it was the cheapest 3600 ram I could find to pair with my Ryzen (which apparently likes faster ram)
oh, i need a cheap reliable monitor to pair it with, id rather pay a little more for something quality than buy something twice.
Also, debating putting off the whole purchase until they come out with the new GPUs, just cause it seems silly to pay big now when it’ll be outdated in a month or so.
pc part picker list
So far my build is just a slightly edited version of someone else’s build I found. At first I was doing my own from scratch but I accidentally deleted the url from my clipboard and decided to just tweak someone else’s build.
Edit:
Friend who used to be a bitcoin miner offered me an old 1080ti, this should be more than enough for Me right?

Since I might be getting my video card cheaper I threw an extra 40$ at my motherboard for the tomahawk.

Bitcoin in enterprise environments

Today Ethereum smart contracts are used in consortium or enterprise environments. For example with besu hyperledger.
When, in a few years, we have smart contracts on Bitcoin, for example with RGB or taproot, do you expect use cases in similar corporate/permissioned architectures? Why (not)?

How can a Bitcoin transaction not use the blockchain? (re: RGB)

I'm researching RGB and trying to understand how the commitment seal works. It's described as a Bitcoin transaction that does not use the Bitcoin blockchain and therefore does not use any block space.

SteelSeries Engine + TridentZ's RGB Lightning Controller = HIGH CPU USAGE

Hello,
I have an i5-9600K on an MSI Z390-A Pro and the sticks are 2x8=16GB of G.Skill Trident Z RGB DDR4 (PC4-25600) 3200 Mhz (16-18-18-38).
For 2+ years everything was fine with G.Skill's Trident Z RGB lighting controller software and my rig. Now (all of the sudden) the process is eating ~25% of my CPU in taskbar (idle, gaming or w/e).
I've done a lot of research - but haven't found a solution. What I have found out so far it has something to do with SteelSeries Engine 3 (specifically the hardware drivers for the headset 'Arctis 7 2019 Edition'), I can not simultaneously have installed TridentZ lighting hid and SteelSeries Engine 3 (or the drivers for the headset), or the CPU eats that 25% that process.
As any user of Arctis 7 headset they know it has two outputs; 'Arctis 7 Game' and 'Arctis 7 Chat', while 'Game' output is the main channel and 'Chat' isn't meant for your audio output.
So if I have those two programs installed (SteelSeries Engine & TridentZ's RGB lighting controller) and select from audio mixer the 'Arctis 7 Game', no audio is heard at all from my system AND ALSO EVERYTHING ON MY SCREEN IS 0.1 frames per second (even if just moving cursor on desktop, nothing else), and as soon as I switch to 'Arctis 7 Chat', (which is worse than 'Game' (NORMALLY)) the lag is GONE.
If having those two programs installed (SteelSeries Engine & TridentZ's RGB lighting controller) and I task-kill the TridentZ's RGB lighting controller other processes (like 'Wallpaper Engine' & 'DisplayFusion') both go to 25% CPU usage - then if I kill those it's W10 processes like 'System', 'Windows Problem Reporting' or 'Windows Remote Procedure Call' process go into high CPU usage.
Before I knew the problem is with SteelSeries Engine (and/or its drivers for Arctis 7), iCUE, Wallpaper Engine or w/e, I have tried to use another GPU, the integrated GPU, installed clean W10 over ten times over, I bought the same exact MOBO as a replacement, tried every RAM slot with every possible combination with my two sticks, used 'Windows Memory Diagnostic tool' for three times, nothing. ...
...A lot of researching and being paranoid if I have a back door (for malware like BitCoin miner or smth) in any of my hard drives or in any cache/memory of any PC-component like CPU, GPU, the RAM sticks, the MOBO... - - - ,,, [!] Since the last three months I have been struggling with this. [!]

Upgrading my 5 year old PC. Any thoughts?

So I've had my current set up since I was a freshman in high school and now that I'm noticing my PC struggle on triple A games and blue screening frequently, I decided to replace my motherboard, CPU and RAM all at once. My current rig and what I plan to replace:
Specs:
CPU: Intel i7-4790k 4.0Ghz --- AMD Ryzen 9 3900x
Motherboard: Gigabyte Z97X-GAMING 7 --- MPG X570 Gaming Edge Wifi
Graphic: ASUS Geforce GTX 1070ti
SSD: 500Gb Samsung
Hdd: 1Tb Western Digital
Ram: 16Gb DDR3 Corsair Vengeance --- 32 Gb Corsair Vengeance RGB Pro DDR4 3200
Power: Evga 850W G2 Supernova
Wifi: TP-link N900 wireless Dual Band PCI Express Adapter
Case: Obsidian Series® 750D Full Tower ATX Case
ODD: Samsung DVD-RW

I haven't changed any parts over the last 5 years except for the graphics card which I got during the BitCoin craze (dumb I know), but I wanted to see if you guys can let me know if the choices I made were good/bad or if you had any experience with AMD that could help me prevent any problems. Or just make fun of how obsolete everything is.

Gaming PC went Fast then Lags in Gaming

Hello all, I'm fairly new to Reddit but I'd thought I'd try it out after reaching out to my PC friends for help and maybe I'd find luck on here. I use my PC for work and Gaming since I am a college student but planning to game and become a streamer.
Here are my specs/setup: CPU AMD ryzen 3990 GPU Nvidia GeForce 1660Ti 16GB Ram Tridentz (8x2) 2TB Hard Drive Seagate 500Gb SSD Samsung Monitor is MSI 27" 144hz 1ms Windows 10
This PC was working very well and fast but over time, I was using RGB for my fans and Razer for miscellaneous setups like keyboards amd mouse... but it didn't affect any performance so far.
Also, I am one of those people who don't want to lose their tabs when I use Explorer (for work) or GX website (great website btw), and I would just minimize it and turn off my computer. When I turn it on, it would have my tabs and YouTube open and ready to go.
Over a week or two, it takes a bit longer maybe 2 minutes top to 4 minutes for the RGB to settle in (used to be 1 minute or so) and as well as for my PC System to allow my mouse to click and type in anything really... and of course Steam always updates itself and automatically opens, then Razer opens but closes immediately (because I made it to close itself so I dont have to manually check if the RGB is on)
Then for some reason Spotify is open by itself (maybe I treat it the same way I treat my Explorer, leave it open and turn off my computer afterwards and it just opens based off of memory?)
I close those EXCEPT my websites that I always like to keep open (i just minimize it), and then play my games. As I gradually play WarZone COD for a month, it started to lag and made my character Teleport places where I was before or forward where it "thinks I am supposed to be". It was very irritating.
My friends suggest Geforce Experience, and I followed their steps about optimizing my games and updating my driver. I got it down. But it still lags. They told me to edit my Resolution in game from 1900 to 2000--still doesn't work. I edit the Refresh Rate from 60 to 144--nope, nothing. I edit my V sync, not much difference. I restarted my PC off and on again, nope. Rebooted to my PC settings to check anything is off like my driver being recognized into the system or not, I didn't change much or anything at all, so that did not work. I checked temperature, it always either cool or warm room temperature. So that wasn't the problem.
I even downloaded MalwareBytes (detection for any malware or viruses) for any bitcoin peeps that may snoop in my PC system, nothing at all.
Its all so frustrating!
I've been on wireless WIFI using Netgear but the internet connection seems strong by 3 bars or 2 bars. I dont know how to check my speed for the connection. My friends shown my this long dang ethernet cable to my router (haven't purchased it), and Im not sure if its my wifi Connection or my windows tabs I keep open because I'm browsing for PC and second Monitor Upgrade and new desk table that I'm building.
Oh, and I do use Discord calling at the same time I play, but it didnt affect my gaming initially anyways. I noticed at one point when I lagged really bad, the discord call cut my voice off and my friend couldn't hear me for a good 15 seconds or so and their voice got a little robotic. So thats where I got my assumption it might be my internet? Is wireless network really that bad? If its not the wireless network, what is?

Banned for trading on unnoficial discord (Be careful of how much you trade on their)

Hey u guys
I want to preface this by saying a few things as Ik ppl wont believe me and will just think that i either bought roubles or sold them or cheated or wtv. I have not done ANY of these things and im not on here to get myself unbanned as I have already sent emails and made support tickets to get my case looked into. I am making this post so that i can raise awareness so that EVERYONE else doesnt fall into the same situation as me and have to wait however long its going to take them to look into my account and unban me. I would suggest that anybody who uses the unnoficial discord or even trading stuff with people you know through twitch chat (something i have done as well) to be VERY conservative with how many trades they do as i believe one or two trades every here and there wont cause you to get flagged and banned but I did alot of trading in the past few weeks as a result of being a solo player who plays alot and aggresively (as well as the fact that i play alot of labs and run into my fair share of rgb gamers with stuff up my prison wallet) I would also be careful of dropping stuff that you have FIR to a buddy ur playing with as 2 raids ago i had gotten a ledx from blue and dropped it to my friend as i was going to push players and told him that if i died he should just leave and sell the ledx and we can split the cost, we played one more raid i got my bitcoins edned up dying and while im waiting for my buddy to get out boom banned. anyways i hope that nobody else has the same issue as me and is careful of how you do trades etc.
