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.
its very hard to do it when your investment is small. if you buy coin at low price and your investment is low i cannot hold a longer time instead trade it with much effective technique just like short trading. yes it is effective when you hodl your coin and sell it at intervals but it is situational, if you have higher capital in trading the hodl matter will be effective.
Yes, we should always manage our investment otherwise it is impossible to control our emotions at one stage, instead of focusing on short term better we need to grab most development coins and it will surely help us to make a decent profit. The low investment will help us to hold the coins.
