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.
You are right mate timing is important the problem is we don't know how to do proper timing in the market that always moving and high on volatility. Sometimes I was thinking that crypto profit depend on our luck because we don't really know when price will change, my strategy is to always get some update about the coin that I wanted to invest and if there is something new about it's development then I will buy it on its current price before it rise up high.
