they let you withdraw staked ETH? the one I have on CB under eth 2.0 said not until 2.0 is released, and the one on ledger said the same thing. Don't know where you pulling your staked eth out of. I think they said like 32 was the minimum to run a validator but with exchanges or lido like on ledger, it lets you group together with other people so guessing thats how I can do it with much less eth.
CB has staking for atom, xlm, dai which is a stable, and I think usdc, but not beneficial since they getting most of the cut. CB is 5% on atom and keplr wallet is 16% just has like a 21 day unbond period I believe but gotta take risks if you wanna make gains.
