Cryptocurrency got this sinusoidal movement, in that no one knows the next increment or decrement. when BTC was pretty low, a lot actually thought of investing on it and when it became $700, they saw it as a huge increment and decided to sell it but now the price of BTC is $18955.89 and those that sold at $700 are wishing if they had knew they wouldn't have sold it. i wonder its next increment in the year 2018.
