high volatility and no real control over cryptocurrency, the bullish trend that occurred in 2017 brought the cryptocurrency market to a level that should not have been achieved last year, too soon for the market to skyrocket. Therefore, some analysts claim that, what we are feeling now (the market crashes), is only the market's attempt to repair itself and bring the crypto back to its proper place.
Any analyst who says different is clearly clueless. There can be a lot of debate about the potential of crypto, but not much about where it is currently. It's not big enough yet to be a trillion dollar market which it nearly was at the end of the bull run.
