there are many ways to start in trading, here some advices i can give to you:

- get as many as possible accounts on exchangers
- set yourself a goal: how much i'm willing to lose?
- diversify: invest a small amount of money in the top 5/10 crypto and start to trade
- sell high buy low (thanks capt. Obvious)
- read, be hungry, look around for news, charts and try to predict what can happen in short term

These points are a must-to-know for a new trader, you will lose money at start but, learn to adapt and read the market and trust me, at some point you will gain something small and that's the start.
Enjoy it but dont get too stressed about dips because this world is a roller coaster and nothing can change it.
