DeFi will head somewhere when the nexus between scam devs and toxic twitter shillers will break. Till then, it is just a bunch of HYIP schemes where you will lose money if you are not within the first 50 or 100 people depending on the size of the project.
Very few of these are actually trying to build value. While looking through some of these experiments, it also becomes doubtful whether there is any scope for creating value or not. Much of the "stablecoin" and "lending-borrowing" market is saturated. Both of these are under the threat of regulation right now. The current run of DeFi had a lot to do with anonymous hodlers of insane amounts of BTC and ETH (Those we call whales), looking to just have some fun after a long year of depressed sentiment. Its just a game for them while for the newbies, its real money they put in.
