The high priority transaction fee now, according to mempool.space, is 97 sats/vB. That's very expensive, I believe it was just a few weeks ago, maybe a month, it was at 2 sats/vB.
Is this really just a measure of how much demand there is, for transactions, in addition to how much mining is taking place? Is there anything else happening? Seems odd that it changes so much, so quickly.
Also if you look here - https://bitinfocharts.com/comparison/bitcoin-transactionfees.html#1y - there's some huge spikes. One particularly on May 8. Are these spikes caused by anything other than the regular causes?
