A lot of the DeFi concepts available today are all experimental and will take time to mature. These projects are building financial products in a decentralized context so a lot of things have gone wrong and could still go wrong.
Yes experimental and very risky. I just hope they could improve the security and priority it first prior to launching cause the actual hacks happened on the codes and some smart ass are able to counter it due to the flaws their able to see and taken advantage off.
Most big defi are being monitored and waiting to be exploit by these guys. So for new projects, I think they should compromise first with the security before doing the liquidity approach and some new ideas they could impart to defi users.
