I feel that in terms of percentage the share is dropping like a stone. That being said, I've never used bisq either
A dropping percentage share doesn't mean it isn't growing, just that it is growing more slowly than centralized exchanges. This is likely going to be the case for a long time yet. Very few people who are new to crypto go straight for a DEX. The vast majority will start with a centralized exchange such as Coinbase or Binance, particularly given how much these exchanges advertise themselves both online and in the real world. When was the last time you ever saw an advert for Bisq? Such is the nature of DEXs without a centralized pool of profit to promote themselves.
Given how centralized exchanges become more and more draconian every time they are in the news - ever more invasive KYC, handing details over to governments/tax agencies/law enforcement, locking accounts, seizing coins, etc. (not to mention all the hacks) - then I think DEXs will continue to grow in popularity.
