Fraudulent exchange. I came across a Telegram channel that talked about making money. I was offered "intra-exchange arbitrage" with the BTC coin. Out of curiosity, I deposited $100. You can withdraw money with a promo code. From one spin, you get an additional 1%. In the end, I had $101. Then they started persistently urging me to increase my deposit, at least to $2000, so it would be "more interesting and they would get a percentage." When I refused, the $101 simply disappeared from my account.
