What would be the real trick with the ETH investments which I think others do not have (and not even eth has right now) is the fact that it is trying to move to staking. So let's say you open ETH investment as well, and ETH has created 2.0 and now it is not proof of work but its proof of stake. What does the website do? The logical thing would be to let you stake on the website, they will have it obviously on their storage and they will stake it for you and give you the money minus some fee for doing all the work right?

Well, on top of that you would be also asking them to use that money as bankroll too, if it is bankroll that means money comes in and out all the time, how do you deal with all those changes while also staking? It is really not an easy task to juggle with.
