For you to calculate the transaction fee of satochis, i don't think that is necessary because is not as if the installed calculator the wallet use is wrongThere are many website that can provide the average transaction fee online. There are some websites that provide information like Satoshis/Byte in order to calculate the Bitcoin transaction fee. However, the problem is that I do not know how to use them and I have no idea how these calculators work. Can someone please help me to find a reliable and easy calculator that any beginner can also use? Thanks.
