I'm on the same boat, around the same tx size and fee
but I was trying to save fees on consolidating many small unspents.
first seen relay time was November 3rd 2017 and still unconfirmed now
I think we need to try double spend or CPFP method
There are currently only ~30k unconfirmed transactions and the mempool is okay again. Not to mention that I had a few 1~10 sat/byte transactions a few days ago (when we had a huge backlog) and my transaction went through after a couple of hours. If you accelerate your transaction, it is almost certain that you will see a confirmation on the same day or the next.
You must be very lucky because all my txs (7 of them) are still unconfirmed for almost a month
did you accelerate them thru antpool? because that's the only one without 400bytes or 10sats/byte limit
I created and used antpool to accelerate them but didn't seem to work? do I need to be a miner on that pool too?
