Hello, I have a cryptocurrency wallet. I was approached by some guy who said that he would trade cryptocurrency for me, and then I'll make a lot of money. He said that he'd only take 15% of the profit. It was a really good deal. So, he said that I was to purchase cryptocurrency and put it to my wallet. After that, I would open an account with a company he would tell me. Therefore, I bought the cryptocurrency and stored it in my wallet. Then I changed my mind about letting him trade for me. I had second thoughts about the guy. I didn't quite trust him. He gave me some magical figures. Now I'm wondering how I can make money with the cryptocurrency in my wallet.
