And now it increased 61k, My transaction is also un-confirmed from 12 hours and i'm waiting for it to get confirmed.
Did you pay the correct fee? which is now an average of 27k satoshi, 120 satoshi per byte, the previous one was 20k satoshi, i suppose it's now higher because there are more pending transactions
He was paying the correct fees before the spam transactions were happening. more and more spam transaction fee will make deprioritize on your transaction. It has needed more time to gone.
Caused by the spam transaction the system will increase the fees without any attention.
