Hey
i want to make some profit by buying ETH cheap and selling whenever it goes up through metamask and swap it into usdt/usdc to safe my profits.
The only thing is that the fees through uniswap are really high, which are like 150-170$ on a 60k swap from eth to usdt on both ways.
is there any other alternative which is cheaper, as i dont want to use any CEX
Why don't you compare swap fees and liquidity across different DEX. Apart from Uniswap there are others like 1inch, Sushiawap or Matcha all of them aggregate liquidity from various sources. They offer better rates and lower fees than onchain DEX like Uniswap. If that is a problem for you then use layer 2 solution as mentioned in the first reply.
