Can someone explain to me how this is possible?
I received an anonymous payament on my blockchain wallet equal to the amount of 0.1 BTC.
The transaction has 3 confirmations, then after 40 minutes i reopened my blockchain wallet, and the same transaction was resent to another wallet,
and i didn't send anything to anyone.
The sent trasaction has yet 0 confirmations, what is happening help me please.
I can be sure that noone hacked my wallet, i just received a confirmed bitcoin transaction and then this man reversed it, but i tought that this was not possible if the transaction is confirmed..

What happened and what can i do?
