Since February 2018, Bitcoin has shown a strange but clear pattern. Bitcoin will fall to US $ 6,000, start a corrective rally, test the resistance level of US $ 10,000, and drop back to US $ 6,000. In the past six months, Bitcoin has repeated this process three times, all in the range of US $ 6,000 and US $ 10,000, and on rare occasions it has dropped below US $ 6,000 and penetrated above $ 10,000. Very likely, in accordance with Tabb Group's findings, a market far greater than the global crypto currency market continues to impact BTC's medium-term movements, particularly in the range of US $ 6,000 to US $ 10,000.
