I sent a transaction of 0.12 BTC with a fee of 11 sat/b. I expected the transaction to take a while to send, like a week, but it's already been almost a month. Is there something I can do to boost the transaction? A month ago I also sent a transaction of 0.03 BTC with a 15 sat/b fee and it took 4 hours to confirm. I didn't expected the 11 sat/b fee to take so much longer...
RBF (Replace-By-Fee) will solve your problem. What wallet do you use? – Monstrum – 2018-01-02T16:10:11.627
I'm not familiar with the RBF. I'm using a Copay wallet. – Daniel Nadasan – 2018-01-02T16:24:13.677
It seems this is an open issue on their GitHub regarding RBF support.
