Mistake #1:
Never engage in medium or long-term trades with shitcoins.
Shitcoins can easily manipulate with the number of supplies and the large wallet hodlers so its ideal to get with the ride on the shitcoins or memecoins and make a quick flip it doesn't have a long term goal unlike the bitcoin and other projects. Reason why people get a ride of the help and sell their asset immediately after taking gains 2x is enough don't take greedy.
Mistake #2:
Avoid overtrading at all costs.
The reason why there's a TP and SL in most of the exchange so this feature makes the trader avoid getting liquidated. If the trade is not well according to plan better to cut loss and make a plan for another execution if there's an any opportunity on the market.
Mistake #3:
Don’t buy newly-listed coins on exchanges, especially if you’re a beginner.
Actually not all the time because like what happened with the meme coin Trump people make a buy once its release and the price goes up to the sky during its short time so if you get ride on the market within these days on this coin you gain profit and if you are late comer you will just get trap in the market.
