There's a small downside to it. Currently the prices at Bisq are so low that people probably won't prefer trading their crypto on Bisq compared to the exchanges themselves. It's one thing if your currency is USD but I don't see many active trades on Bisq for other currencies. There just aren't enough people trading on it just yet. I've installed Bisq since more than a couple of months now. I'm positive about Bisq, just that the actual usage isn't significant atm.
