Bisq is interesting, but, being a user of many cripto currency exchanges, it is too complicated for a simple user to trade on it, too many buttons that nobody know what is used for. KISS (Keep It Simple Stupied). I´ve been watching and the volume of trading never increase, it is always the same. If it become a simple version it will grow, otherwise it will always be this small market as we see everyday.
Everything that you see wrong with Bisq is a chance to help. You can reach out to the community on Slack to help.
it is growing and just like all technologies it will get easier and people will get used to using it
