do you think they would stake with customer deposits? that seems unlikely from a PR standpoint, right? the optics are obvious horrible with sites like yobit because they literally block withdrawals for weeks while staking. it seems pretty sleazy even if customer deposits are always available, but is it unacceptable behavior? i assume cold storage staking will be possible in ethereum.
I'm sure that Coinbase, as money hungry that it is, will find a way to allow users to gain the benefits of it, all to not have them withdraw their funds. If Coinbase even gets to keep like 2'ish % of the rewards and whatnot, it's an extra revenue stream they otherwise wouldn't have. It's all in their favor to have people not withdraw their funds.
I'm however not sure how they will deal with voting rights, but that's probably not what most of the people storing their coins there are worried about as long as they are rewarded accordingly.
