I haven't trade any coins there yet, but my friend said you must have at least 0.05 - 0.1 eth. You must prepare enough gas to buy any coins on Uniswap, mate.
I think 0.05 - 0.1 eth is not too much to provide, because it could be the effect of gwei costs from the erc20 platform which is still large and unstable until now, so uniswap users have to provide 0.05 - 0.1 eth to buy coins there.
quite expensive for a transaction when compared to last year. In the past, in one Ethereum transaction, we would only pay very cheaply. but now maybe things are different.
Uniswap does seem to have quite an expensive fee. especially with the unstable condition of the ethereum network. Two days ago I had intended to sell my tokens on Uniswap, but due to the high cost, I thought I would discourage me and decided to wait for everything to become normal.
