That is if he is a real trader or someone who just heard he can make money from trading and then decided to hop in without any knowledge or strategy whatsoever to trade the market. Market is always bound to be volatile and most especially the volatility is high with the cryptocurrency market which is the reason why you just have to be very vigilant, know what you are doing, and make decisions without emotions but what you know and what you see.

I have never entered a position based on signals without ending up setting a stop loss, and that has always saved me from falling markets if the trend decides to continue downwards as against thinking of a reversal.
