I also tried to buy some shitcoins from uniswap and catch some profit. But I don't think it's worth for the person like me who have really small amount in hand to do some trade. The fee is highly insane. Yesterdays I tried to buy a token of 0.5eth, The gwei was 145. It almost took 7$ of my wallet as fee. That means I am already on 7$ loss. So, I don't think it is worth for me I would rather go to binance and try some day trading.
