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.
This is some quality advice. Pay key attention to point number 1. Invest what you are comfortable losing, if things go southwards, God forbid. Before jumping into any trade, make sure you research deeply and you'll surely come out a winner.
