I received a tiny BTC deposit in my wallet recently. I don't know where it came from and I hadn't sent or received to or from my wallet in about 2 weeks before the deposit. Could this be something to be concerned about?
I'm afraid you've been hacked. Those coins are a virus and you've now been infected. Next time you log in your balance will be sent to the ghost of satoshi.
Seriously, you're a hero member and you're worried about someone sending you bitcoins?
It's most liklely nothing but blockchain spam.
