The strategy which Institutional investors use to hide the real size of their bitcoin trades is unveiled. Major exchanges help them to do so – to cut the risk of exposing their intent to the market which can lead to unfavorable price moves. Recently, Avi Felman shared one such trade when an institution bought a significant amount of BTC on Coinbase. The order book only showed buy order for 20 to 40 bitcoin but a larger quantity purchase was made through small orders.
