First off, as many people here have already pointed out, you need to figure out what type of marketing works best for your crypto, and that includes getting it into the right people as well, those that will be more interested into buying your coin more than any other people. Social media's been so powerful these years that you can do all of this in a snap of a finger, in the very same platform you're advertising your cryptocurrency. Figure out how that works and when you play your shit right, you should see a shoot up in cryptobro interest once again.
Another thing you should look for is the density and quality of the use-cases you're trying to sell. Are you looking to revolutionize the industry? Or are you going to be yet another crypto shitcoin project with a tradable NFT system to be implemented in the future? People are becoming smarter nowadays and are not willing to settle for less anymore, reinvent how you want to serve your people and you should see a recovery.
