Entering 2017, the Bitcoin BTC bull market came, and Zhao Dong's OTC trading became even more popular. I remember that when it was the best, it was said that he could make millions a day. Bitcoin BTC rose, and the group was very enthusiastic. I joined an OTC trading group, and every day there were a lot of how much Bitcoin BTC was in/out messages rolling. ! Before September 2017, there was no USDT, and it was more troublesome to deposit funds into the exchange. I remember that when I bought coins, I had to transfer money to the account set up by the exchange. In order to circumvent national supervision, the exchange will register many companies, and the accounts are often frozen. Once I transferred money to the company designated by Huobi, but it didn't arrive for a long time. I searched the name of the temporary company on the Internet, and a lot of people said it was a scam company, which scared me to death.
