The DeFi market is bleeding but everyone is not affected by it. Some made a good amount of money in this hype and exit when they have profit. DeFi just slows down and it's not the right time to say its just a bubble. It could be a whale's market manipulation so that they can buy them at a low price. DeFi project has practical use so it's not totally worthless.
Not all of the DeFi projects have a practical value, some are just like those ICO tokens that were not good for anything and still got millions in the ICO round with the help of public hype. I guess it is the cleansing round where the market is under correction and once it is done then only those DeFi projects will remain which are having a genuine use like Link, UNI and BZRX token both are good tokens and have a good future as well and the price is surely gonna rise with the increase in number of users.
