It's a little to late to tell you to opt-in rbf... But next time, make sure you opt-in rbf
In your case, there are a couple things you can do:
- I see 2 outputs, one is probably going to your change address... You can do a CPFP
- You can use a free accelerator... AFAIK, viabtc still works but needs a minimum fee of 10 sat/byte (and you payed 3 sat/byte), but you can still submit it to antpool. Antpool gives those transactions a higher priority, but in case of a very low fee it still won't "solve" your situation
- You payed 3 sat/byte, the mempool usually clears during the weekend... If you just wait your tx will probably get confirmed... If it doesn't get confirmed over the weekend, you can rebroadcast it next week
- You can pay a big mining pool like viaBTC to include your transaction in the next block
- You could try to double-spend the unspent outputs used in this transaction and create a new transaction with them, funding the same address but with a bigger fee... Difficult to get it to propagate trough the network tough
Realistically, your options are:
- CPFP (quasi guaranteed fix + fast)
- antpool's accelerator (no guarantees + slow)
- waiting, eventually rebroadcasting (quasi guaranteed fix, but it might take a while)
- paying a big pool operator (quasi guaranteed fix + fast)
Like i said in the beginning of my post: make sure your wallet sets the rbf flag in the future, avoid these kinds of problems....
