The tools quite useful, but I don't needed it actually. Peoples might need it when they need the fastest transaction. Anyway I have two transaction today and all I have to pay for fee is 0.0000129 (for two transaction) and got confirmed less than 3 hours. But for me as long as the fee is low, its better.
This information is very useful, I hope there is a website on Google who can give information about Bitcoin and Ethereum fees clearly and definitely. Or maybe some of the people here already know about this and know the website? Maybe you can tell me. Currently it is very important for us to pay attention to the fees in every transaction that we do. Because sometimes we ignore it so that our money becomes less than we anticipate. And also do not just do transactions especially less important transactions. Try to do transactions at once and do not do transactions gradually. I think it would be more effective for us to do a one-time transaction if that is necessary. And do not do the transaction in small quantities.
