I was going through a blog from bisq and I found out they respect privacy
Yeah, I can confirm this because I use both bisq and bisq2. Among the different payment methods bisq2 supports direct person-to-person trades during in-person meetings if you find someone relevant to your local area who wishes to exchange BTC for cash. This “as old as the world” way of cashing out stuff doesn’t leave any trace on blockchain.

Regions vary. In some, P2P exchanging bitcoin for cash requires a lot of luck and a big balls to avoid being smashed by a $5 wrench attack during the exchange.
True, there won't be any trace left on the blockchain, but you can be tracked in the physical world, where it's hard to get lost among online nicknames.
Furthermore, not only criminals but also law enforcement officials with test purchases may attend a P2P exchange meeting (remember that the legal status of bitcoin remains in a gray area, and in some cases, even outright illegal), and in particularly interesting cases, these two elements may be combined.
Often hear about bisq as a panacea for solving privacy problems. But is this really true?
P2P exchange "like the good old days" will never happen again. Now, we need to approach this activity with extreme caution.
