By "stacking" do you mean "staking" or the full sense of the word? If you mean staking, then I wouldn't recommend doing so on a centralized exchange. You can easily get your coins lost as a result of a hack or the exchange closing up shop. If you really want to stake ETH, then your best bet would be to stake it on a decentralized staking pool (like RocketPool). Or you can stake it on Uniswap's liquidity pools if you want. Gas fees continue to be high on the main ETH blockchain, so staking a few dollars worth of ETH will not be enough to make profits. I would seek other alternative blockchains like BNB or SOL to maximize my chances of earning money in every way. As long as you don't invest more money than what you can't afford to lose, you'll have nothing to worry about. Just my thoughts
