He made all the losses from playing stocks. He encouraged me to invest in cryptocurrencies. At first, I invested more than 10,000 yuan to earn a little bit. Later, I invested a large amount of money. Li. Until recently, I wanted to withdraw coins. The customer service said that I could not withdraw coins due to abnormal transactions. I didn't know that it was a fake exchange.
