i did some google search ,turned out a site with name vivigle who sent it , i don't care if this just advertising , it's funny ,
that's really strange to tell you honestly, you might be joined before in bitcoin faucets then it just sent to your wallet, but to send it to your wallet without any reason, that's really insane and ridiculous mate. Well, if that's really true be thankful at least you experienced that kind of free bitcoin to your wallet.
