the most important thing is don't be greedy many of us lose just because we are too greedy. so the first thing is to always focus on the targeted profit you want to achieve, don't be too big or small. after the target is reached you must immediately sell it. don't think the price will go higher (this is what often makes the trader lose).

second, always trade on coins that have a large merketcap, coins with large merketcap are difficult to manipulate (even though it is not impossible to manipulate, this is only to minimize the risk of loss).

and third, don't be influenced by any speculation. even if it's said by experts. we just simply trust news that contains facts.
