Since I sent twice to Same address and one transaction is still unconfirmed that's y second is also not counted. Thaymos looks into the matter and resolved it.
Maybe you can't wait for the Bitcoin to be confirmed, so you send it twice.
You should add costs before sending the Bitcoin to get to the destination quickly, not sending twice the same amount.
Then how about the bitcoin that you sent for the second time, can it be returned?
Probably Yes.
I guess Theymos would consider it was a human mistake.
