When you can't understand the working of this market, the volatility of coins which gives you more loss than profit at such condition people move out from cryptocurrency. But I will not blame crypto currency as this is the fault of people as they invest at right time and in right project. Newbies tend to listen to anyone pretending to be expert and lose their money after not properly searching about particular currency. If people study before investing they will never move out from cryptocurrency.
One of my biggest annoyance since the 2nd half of 2017 is how many new Youtube channels there are with 100s of thousands of subcribers, brand new channels, giving people advice. Telling them, "Buy this coin because it's really hot." While old, good channels, with good trading experience and information are stuck with only a few thousands.
