A famous digital currency analyst with the nickname Jack Sparrow believes that the old cyclical model of Bitcoin, which operates on the basis of the 4-year cycle of Bitcoin, is no longer valid.  He says the cryptocurrency market relies too much on past price patterns.  This analyst believes that Bitcoin has entered its maturity stage and its price behavior will undergo fundamental changes.  He sees September as a defining month for Bitcoin that will determine whether the upward trend continues.  According to this analyst, the $61,000 level is key for the continuation of the uptrend.
