I made a mistake doing business with someone here, had given a wrong btc address. Why wrong? Naturally we all assume the btc address that someone provides is their wallet address and care to say wont do the search. Which this part is my mistake as well.
The actual transaction amount was 0.02164 - so this is another mistake for not double checking your "0"s.
Outside from the point the btc can sent back, if it was in their balance. So then I naturally assumed it was their btc address. The double screwed up part is when they provided a gambling btc address instead. Regardless if I sent the right amount, they would of never received it.
Overall summary:
1. Always check the zeros in sending btc amounts (triple check)
2. Check the btc address prior sending any btc is not a gambling address
Edit - since I got a lot of response based on this - just to clarify it wasnt for nothing - I sold a spare btctalk account to "Candystripes ". He sent me the wrong amount and I said I would send it back. Then provided me with a btc gambling address, which I sent.
I've learnt that the other way but yes, I'm always double checking the price, the adress... I lost about 1000 dogecoins because of sending them without checking.
