The point is there may be some people buying bitcoin so they can have it wrapped and get rewards which could have contributed to the pump. It's possible that thousands of btc's were bought from or taken off exchanges and temporarily locked on these "interest" bearing platforms. You get what I mean?
It is a risk taking activity that I don't do. Take risk, and exchange a safe asset to take a risky one (lock and get a virtual number to get interest). People who love risk will like it but I don't.
Buy bitcoin, store and hold in a non-custodial wallet is safer than lock it on any platform or hedge to get interest.
