Why I made this tool?

Transaction fees suggested by bitcoin wallets often are very high, but setting the lower fee manually can be tricky. If your transaction is not urgent and can wait few hours to be confirmed, you can save a lot of money by choosing a lower fee. But how to pick the optimal fee to make sure your transaction will be send?

Current waiting times for each fee can be found on https://bitcoinfees.21.co — on the left side you can see fee ranges in satoshis/byte. Satoshi is 0.00000001 BTC, but many wallets display fees in other units, eg. mBTC/byte, BTC/kB and so on. This converter will help you figure out your fee in satoshis/byte, to help you choose the optimal one from the graphs on the above-mentioned page.
