Okay thank you. So what can I do now? Is it possible that my transaction will stuck forever? Apparently I'm not the only one with a 80 satoshi/byte transaction. What can I do?
Your transaction is 100% not stuck forever. The only problem is that is going to take some time to get confirmed, but it's getting confirmed for sure.
I expect a tx with fee of 80 sat/byte to take at least ~12 hours or 1 day to get confirmed. Also, there is nothing else you can other than pay someone to manually accelerate your tx, so just wait.
