Do you really look for a long term profit, like the people who had bitcoin in 2014 or are you here trying to get a quick buck with a minimum effort?
I only believe in bitcoin as a long term investment because it is the original crypto. I am scared to invest in other coins because I dont trust them. But of course in holding coins I always check the price chart and predict whats happen next, if my analysis on that particular coins is nice. I would hold it until it profits high.
