try trading major coins, check news on the coins.
if now news observed - use technical indicators (e.g. Ichimoku) or support/resistance levels.

try day trading - and create a trading plan: how much are you planning to each all in all and per trade; how much you can lose (and probably set a stop loss); how long it may take approximately; and follow these rules.
and also trade calm and cool. trading is a real stress and adding more of it will cause bad things to your health and your trading.

and practice, practice, practice. that will make perfect
