for staters, invest within top 20tokens first, observe how the price for the tokens vary. then start predicting with the help of your judgement and others judgement (your peers)
if you are a complete beginner, do not put your money just yet. instead, do a virtual or even manual practise trade.
also.. it is better to know the basics of trading and master it.
even the best traders lose because they've missed the very basic of trading.
goodluck.
