When looking at the "Predicting Bitcoin Fees" website (bitcoinfees.earn.com), the current recommended fee is 20 satoshis/byte. However, most people have been paying a lot more than that, including 8000 transactions paying over 180 satoshis/byte! Who are these people and why are they paying that much? I sent one transaction today and one yesterday, and they were confirmed within a couple of hours paying only 2 satoshis/byte. With SegWit, those transactions came out to about 3 and 5 cents respectively. Oh, how times have changed!
