Bitcoin transaction fees rising because the last block took over an hour to mine.
As you can see there is a brake of 1 hour+ between block 507001 and 507002 this lead to a clog up of the mempool and a rise in transaction fees as seen in the second picture:
So right now to get a transaction through you have to pay 140+ sat/byte. which is insanely high. Sadly the next block keeps waiting. 24 mins and counting.
