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?

Never. Because bitcoin addresses has too much numbers and letters in it. It also has some big and small letters in it. So there is 0.0000001% in your entire life to receive random bitcoin to send it to your account. Thats my opinion. And mostly bitcoin users tend to use copy and pasting addresses in sending bitcoin.
