These paid transition accelerators do not work and you are only paying someone to do the exact same work as the frendly poster mentioned above.
Save you money and do it yourself and let this be a lesson in BITCOIN txt fees.
The legit paid accelerators work but the cheap accelerators like the one posted by adriano could be a scam.
In that case, what happens when a transaction is not re-boradcasted to a network? Does the transaction get reversed ?
I have read somewhere that when a transaction with very low fees is boradcasted it stays there for a long time and then is revered to the user's address.
Also, why is it necessary to re=broadcast the transaction only in hex format? Why can't a transaction be re-broadcasted as it is?
Yes, there's a possibility that the transaction gets reversed when it doesn't get confirmed for a long time. I don't know how long but when I experienced it for the first time it lasted for a couple of days before it disappeared on the explorer.
