Alright, what I am still confused on is the Chinese Mining Pools. China banned Bitcoin & Bitcoin Mining in its country so how do Chinese Mining Pools still exist, are these pools located in China
China banned the business of mining bitcoin. It didn't ban the software itself. Mining pools aren't miners that require huge amounts of electricity to operate. They are servers that you connect to and direct the hashrate of your ASICs to.
Okay lets use an Example of Bisq Trading for better understanding: I am Seller that have 1 BTC for sale for $50k current market price ask. The buyer likes to buy 1 BTC at current market price too at $50k. So me as a seller has to put up 20% deposit that is 0.2btc and buyer also has to put up $10k deposit.
Only bitcoin is used for security deposits, not fiat or other cryptocurrencies. Both you and the buyer would need to provide an extra 20% in BTC on top of the trading amount. If that amount is 1 BTC, both of you would have to lock away 0.2 BTC as security deposits.
Then we have 20 days remaining to settle the balances on both sides that is 0.8btc and $40k regardless of what happens to the btc market price during that time?
You have 20 days to settle the trade whose conditions you both agreed to. If that means that you will sell 1 BTC for $50.000, then that's rate that will be used. It's in both of your interests to settle the trade asap so as not to get affected by the volatility. Trusted traders will do that.
So for example during those 20 days if bitcoin market price goes to $1millon per btc I have to sell at $50k to the buyer and vice versa if bitcoin price crashes to $1 per btc the buyer has to pay $50k for the btc otherwise either seller or buyer lose their deposit after 20 days you mean?
You can back out of a trade at any time before the swap process is initiated. Once it is, it goes without saying that you have accepted the rate.
So for example if I refuse to sell my 1btc for $50k then the buyer gets my 0.2btc deposit after 20 days?
Most probably, yes. If I am the buyer and I have paid you the $50k we both agreed on, and you said, I am not happy with that and I want $55k or $60k, then that's not the deal we made, is it? I would object to that and most probably the arbitrator would agree with me if it came to that. It's you who didn't respect your end of the deal, so you are paying the penalty.
However you said for any Bisq trade to start the buyer has to submit their key/signature 1st meaning they sent the $40k outstanding balance to the seller and if the seller refuses to sell transfer the remaining 0.8btc after receiving the $40k cash then the seller just loses 0.2 btc for $40k you mean while the buyer gets 0.2btc and his $10k deposit back?
Forget about the signatures if that is confusing you. The signatures are needed for the security deposits and the traded BTC to unlock and reach the target destinations. In your example, they are needed for the 1 BTC to reach the buyer and for the 0.2 BTC security deposits to be returned to you and the other party. The fiat is never locked in security deposits because the buyer pays the seller directly via bank, e-wallet, or some other means.
After 20 days the deposits goes to an address that Bisq controls, controlled by Bots or Human Bisq employees and at this stage after 20days both buyer and seller lose control over the 2 keys and now the deposits are in Bisq control? Humans have access to the destination addresses where the crypto is moved. The trading partners lose access because they failed to close the trade within the 20-days timeframe. I think if altcoins are involved, this timelock is only 10 days. But that's not important right now.
However how does the Arbitrator determine whether the buyer has sent $40k or $4 to the seller?
Based on the evidence that both sides provide. The arbitrator would contact both sides and talk to them. They will surely ask for evidence. If the buyer says I paid the $50k, they will have to prove it. If the seller says I didn't receive anything or I received a smaller sum than what we agreed to, the seller would have to prove it. Don't ask me how they do it, that's a question for the arbitrators.
Bisq Escrows/Middlemen, Bisq wallet address that bisq controls, the mediator and the Arbitrator, are they all humans working for Bisq that do this as kind volunteering work otherwise what are the Bisq fees for using these services and what are the fees for transactions leaving & entering the 2/2 multisig address?
They are humans. Each trade has market maker and market taker fees. I assume they get paid from that pool.
