Yeah, probably an offshoot on what had happened to FTX and that is why many investors are withdrawing right now and doing self custody. But we don't know how long this will take though, maybe again because of this event and once it is forgotten in the next couple of months, everyone is going back to it's norm. Depositing huge amount of bitcoin in exchange for whatever purposes they have, trading, etc.
So this is not yet final in my opinion, we need to go back and see the data maybe in the beginning of the 2nd quarter next year to see if everything has settled down a bit.
Definitely agree with you on this, people tend to forget too early what happened in the past and also greediness plays an important role in this kind of decisions : some really tempitng offers by some reputalbe exchanges ( applies to protocols as well) like two digits interests on stablecoins and a general acceptance of them as if they were normal and sustainable in the long run will do the trick again.
