Remember that to get those yields you need to provide liquidity, which means you have to buy both tokens from the pair.

Buying ETH is no problem but the second token... Things like Pickle or Yfv can have a massive price drops and if you don't monitor it 24/7 you may end up holding worthless token. So it's a casino :)

I recommend using pairs with stablecoins, like ETH-USDT and farm those additional platform tokens (Uni, Sushi) with those pairs.

ETH-USDT gives around 50% APY now on Uniswap.
