And learn to analyze charts because it is important in trading.
No be afraid to trade but always be responsible of what you trade, have some risks management and lastly it's hard if you don't have a plan.
Trading is the art of crypto world So first learn what is trade and crypto market. There have a lot of ways for learning the trade on google or youtube and this forum is the best for learning crypto also. You are Newbie so i recommended to do not invest money on trading first try to demo trade and follow the trading chart. Demo trade increase confidence and also help to learning because practice makes a man perfect.
OKEX demo trade is a good one for starters, I really recommend that. The best learning is experience, yes you can learn on those platforms but if you just into the tutorial purgatory you'll never be able to learn the best one to learn on real world market where you involve your hard earned money, the dedication to learn goes on.
