I no longer prefer to hold my coins to be honest. I was really keen to hold them initially when market was in good phase, but given the current phase of market, I do not think it is worth anymore to hold a coin for a longer duration, say 1-2 years. Better to get rid of them whenever you find the price to be right.
I totally agree with you, because you need to sell only at the best price. But if you look at the cryptocurrency market today, then its not worth talking about sales, because you dont want to give your coins for nothing.
