On December 28, 2020, under the guidance of Wang Shengtian and Long Haichen, I deposited 2,000 US dollars and 7,000 US dollars on the WEINIAN platform and started to operate Bitcoin (exchange rate 6.9). After that, I added funds several times under its guidance and abetting operations and liquidated positions several times. Loss, the process is as follows: the first artificial manipulation: after the temptation to add funds on 2020.12.28, under the leadership of Long Haichen at 26696.77 to buy long orders, 20:10 After being forced to instantaneously liquidate the position at the price of 25832.54, the trading situation at that time was checked on the regular MT4 platform. The index fell to 25838.46 at most and rebounded and finally closed at 27068.4. Therefore, the operation at that time was artificially controlled.
