So, I'm actually surprised they've taken this move, given the ongoing uncertainty of staking regulation in the US right now , however as one of the biggest VC firms in crypto, i dont doubt they know what they're doing I guess...
I have played around with liquidity provision, seems robust, but havent tried staking or unstaking eth yet - it seems they're simply betting on Shanghai being a huge success, in order to offer instant withdrawals, basically lending against their own assets to offer convenience I suppose
That seems to be DeFi solution and regulators attacked CEXes that offered staking services (or just interest, not real staking). So real staking might be safe to do and not everyone want to set up validator nodes by themselves.
I haven't staked eth either by setting up a node but i feel it could be worth it in many ways.
