the best way to gain is when it dump this is the right time to buy and when it pump the best time to sell in this kind of strategy you gain a profit that you want, but if you are a day trader better to go on flow of the market but be careful especially to those coins that pump and dump because its too risky to join in them.
Of course, there have always been artificial manipulations on the market, but how can you determine those coins whose prices are artificially increased or reduced? It seems to me That it's quite difficult to determine, Because if it were otherwise, the results in the trade would be much luckier.
