You barely earn with cloud mining and it's a good option that you have stopped using them. The rates from exchanges really varies and whoever got the most, they're the ones who attracts most of the users.

But I would be away from staking through exchanges, if it's possible to stake to a wallet, that will be my better choice. But I'm impressed with your strategy and you're running all of them at once.

Do you have any estimate how much you earn if it's on the daily basis?
