The first currency to buy is the TNB. Because it is a novice, I missed many opportunities to get rich. I want to cry without tears. When TNB is $0.015, my friend asked me to buy it. I didnt buy it. Later, 0.1453 When I entered the market, when I went up to $0.2906, I still didn't sell it. This time I won't miss it again.
From my experience, Not selling would be another bad idea. A good trader needs to keep rotating his funds among different promising coins.
Similar thing did happened with me. I bought a coin for $0.02 went upto $0.11, I didn't sold but now it's below $0.02 so my profit for waiting 6 months is zero.
