i am not a trader but i see some strategies of long term traders who make a deep analysis of a projects coin before they make a bulk buying and usually they do it before the coin became popular to many users.
Short-term traders don't use fundamental analysis. They usually just play with the charts to predict which coins will be pumped, even sometimes they will read and follow some coins's news. Also, they don't really care bout fundamental things as shitcoins can be pumped as well sometimes.
So, since the market efficiency is still in a weak form (I believe so), just pick the coins in a big exchanges that have been too long in a dip, wait them to be pumped then make some profit from them.
