A few generic beginner tips that will help you to get up to speed:
1: Never invest more than you can afford to loose.
2: Buy the dips (looks easy and is quite easy, if you can resist huge green candles / FOMO)
3: Begin with trading CMC top 25 coins, to avoid to much risk in the beginning.
4: To get the best average price for long term holds, apply dollar cost averaging (buy fixed amounts each weak, and buy a bit more in case of a sudden dip)
5: Bitcointalk, youtube and Google are your friends. View and read a lot about trading to get the hang of it.
6: Do your own research on a coin. never just jump in based on some social media hype.
Hope this helps a little.
Pretty much everything you need to know.
Bottom line, study how the system and market works. It's a gamble out there. You can either earn big, or lose even bigger. The risks are just lurking around. But these are things you need to overcome if you really want to earn once you jump in. So, are you bold enough?
