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
Try using metamask, It's give you total Estimated fee and gas price and it's more safer and easy to use, If you want less fee try to check total Gas used on token transaction and you can see how much gas used for that entire txn. Well it's more simple to use metamask, better use that since some dApps was connected using Metamask, Good luck!
