I am very cheap with fees. I've been waiting since Feb 16 for a BTC transaction that I sent from 1 wallet to another. The fee was 8 sats/byte. I'll report back when it confirms because this is already a record long (13 days)
Your transaction fee with 8 sats/byte is quite low, presumably that during the days you'd make a transaction is a peak day of the mempool network.
However, it barely happens that the mempool network will drop transactions, it's commonly be confirmed but it will take approximately 2 weeks for you to wait. Just keep trying to accelerate your transaction using Bitcoin accelerators, it might help if you get lucky and I suggest using ViaBTC as I have heard, they owned mining pools.
Let us know here if ever your transaction will beyond 14 days.
I used to pay 25sats but still, it takes longer to confirm. That much longer if we only pay 8sat, but probably 14 days is not enough as the fees for now still high.
What I can suggest to OP is to increase the fee( last option), 35-40 sats is fair enough for the miner to prioritize it but of course, it can't be instant confirmation, we still are expecting hours. This be easy when using an Electrum wallet.
My 8 sats/byte transaction from Feb 16 just got confirmed a few hours ago.
The funny thing is that I've been doing 20 sats/byte on other transactions and those are only taking 12-36 hours. Can't believe this one took 3 weeks!
