By the way, I'll quote the words of teacher @Loki_Zeng
"ETF Staking seems to be a potential benefit, but in fact it is the last thought of the $ETH price. Big funds use USD at 5% of the capital cost to buy your 2% APY Staking ETH, brackets, and the management fee and custody fee have not been calculated yet. Is it because your brain is stuck in the door?"
