Hello!I want to ask, if a transaction is confirmed but unsuccessful, can the request be returned to the balance?
What do you mean by "confirmed but unsuccessful"?
Did you withdraw from freebitco.in or deposit to freebitco.in? Do you mean you used a wrong address for withdrawal/deposit?
Note that all bitcoin transactions are irreversible. In the case you have withdrawn or deposited to a wrong address, there's nothing you can do.
I downloaded from Freebitco.in and wanted to deposit in Payeer,but I later found out that the minimum they accept is 0.00050000btc,and mine did not have so much.I didn't get anything in Payeer.If I contact Blockchain support won't it help?
