So easy to say but very hard to follow Especially for long term investors. It's never a pleasant thing to invest in a coin and then watch your investment go low. I have come to realize that in any situation of the market, patience is much needed and also your choice of coins for investment and time of investment also matters. A simple way out is to plan your funds, dont fomo, buy at more dip, take profit at intervals.
Without the character of having a patience, I think We cannot able to earn here for sure. Once you buy of the coins in any of the exchange platform We as an individual traders must supposed to patience at all time and have a self-discipline and know how to control or manage our emotions anyway.
