has it ever happened to u that u just had ur wallet opened and suddenly some BTC arrived out of nowhere?
like someone sent it to the wrong address or something?
like suddenly 0.3777 BTC are rolling in but u don't know who sent it, why it was sent and what it is all about?
~CfA~
Eversince I haven't yet recieve any bitcoin from unknown wallet address even just 0.00001 satoshi haven't

But if ai receive any amount specially if it is big amount well I will not gave it back to him

Lol I think most of the people will do the same, as if you receive very high amount accidentally then you may get greedy and won't take any decision ethically.
