Someone from the social network offered me a btc mine through his mining device. He asked me for an email address so he could create a mining wallet address for me. I gave it to him. I don't know what he did, but very soon after that I received an email from Blockchain informing me that my wallet address had been created and that I could connect it directly to the mining stream. After this I should deposit a certain amount of btc to this wallet address, which is now, supposedly connected to this gentleman’s mining device. is this a scam attack or ..
