If you ever have a BTC confirmation issue that has been going on for days, do not despair...
Try to accelerate it for free with
https://www.viabtc.com/tools/txaccelerator/ or use a paid version by doing it yourself with pushtx.btc.com/#/ but there is a paid service for faster confirmation. I can help with that but it's not free but cheaper than most paid btc accelerators out there. If interested you can reach me or drop me a message and I will respond promptly.
P.S: it's a pay after service has been rendered and confirmation of your btc has been done.
I've never tried it and it does not make sense. Surely many people who do not believe if not used successfully. I chose to raise the bitcoin delivery fee to get a faster deal. In my opinion it will be more normal and does not interfere with the blockchain system indirectly. Because basically the use of bitcoin is anonymous so we do not need third party services to speed up delivery.
