I am about to buy some erc20 tokens, but the purchase would be a couple of hundreds USD each
I'd like to check the transaction costs, amount of gas needed to see if it makes sense for me
i have read that metamask provide you an estimation, but I am not using it, using MEW instead
tks
If you are looking for the gas tracker
https://ethgasstation.info/You can also try to create a calculation about that too through the gas calculator that already provided by ethgas station. I guess you can try to take some latest txs on etherscan to give you an example about which is recommended fees that you can get it.
Any service was using different formula but i think it's better to use mycrypto instead mew because it can give you automatic calculation about gas fees.
