Makes sense. But I don't see people thinking on that possibility if they have already left BTC live on Coinbase.

People either buy on Coinbase with a plan to take it out at some point or leave it there forever. There is no mindset transition between the two that I could find among friends.

And investment platforms also offer that transition to another investment platform. It doesn't change the Custody in the way we know it, but people think it's the same thing.
