how to cancel unconfirmed transaction in blockchain.info
I upped it to 0.00011 but apparently that amounts to about 57 sat/B which is way too low to get confirmed in a timely manner.


According to the 21.co fee estimator:

A 57 satoshi per byte transaction should be confirmed within 35 to 600 minutes (10 hours). It should go through.
