What's counterintuitive though is that buying without KYC and without 'bending the knee' actually allows you to make more money. On one hand, you have no risk of someone 'closing your Bitcoin account' (exchange account), further you avoid pretty high withdrawal fees that cut into your profits (you actually start at a loss if buying on a CEX and withdrawing)
There are also some other things worth considering. I have found that the exchange rates on decentralized exchanges are usually a bit worse than on centralized ones. So the money you would save by not paying withdrawal fees is lost due to a worse exchange rate. Then there is the question of the security deposit. I think new users who play around with DEXs for the first time are displeased with the security deposits. If all you have is 0.1 BTC and you want to trade all of it on Bisq, you can't because a piece of that pie has to be deposited as a security deposit. However, the positives still outweigh the negatives.
