I've just attempted to send some bitcoin between 2 wallets and the amount received in the receiving wallet doesn't match the input, can someone explain why?
Here is the transaction https://blockchain.info/tx/53d1083c08eacf36629f544d19546199029a6fc461215a73a07c7c4adb01a7c2
The input was 0.0032 BTC, the fees were 0.00050278 so I expected to see 0.00269722 hit the receiving wallet. What looks to have happened though is the output was split and I actually received 0.00069722 BTC and the 0.002 BTC has gone to a wallet that I don't recognise.
Can someone shed some light on what's happened? Why the 2 outputs? Looking at my previous transactions it's always been a 1:1 input/output relationship.
I know it's only small amounts but keen to understand whats happened and where I can retrieve that 0.002 BTC.
Cheers
