Wait patiently for the real perfect trend in the market, and don't make predictive interventions; "Timing is important", buy at the right time, and sell at the right time.
Trading is not something to do every day.
Those who think that they need to trade at any time ignore a condition, that is, trading requires a reason, and it is an objective and appropriate reason.
Timing is very important but even expert having a hard time to get the proper timing. Many investors loss because they don't know the proper timing because the price of every coin is not stable. It is always possible that after we sell the price starts to rise up high and we don't get the proper timing that is why we loss profit and this was already happen again and again, in short most of us as a trader and investors sometimes depend on the situation or in our luck to earn in crypto.
