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.
indeed, to do so there are always obstacles that will occur, not all with the analysis that we through the theory that we have in practice will be the same and can even happen to be the opposite. I agree with you that it is not fun to happen when the investment we have actually decreased not ccording to what we expected, but in crypto we actually have to instill from an early , that it is very possible and is not a strange thing.
In theory, it is true that buying when prices fall and selling when we consider it worth selling, but in practice it is not easy.
it could be wrong to anticipate because the most basic things are greed and panic.
