According to CoinMeta, Jiang Zhuoer, the founder of Leibit Mining Pool, stated that since the rise on BTC on August 20th, there has been no significant pullback in the market. The concentrated liquidation area around $76,000 below is larger than the area above $83,000, making it easier for the market to reach the lower liquidation zone. This magnetic attraction effect is the reason why Jiang Zhuoer sold all his BTC positions at $82,000 the day before yesterday.
