and what need to learn for be a good trader ?
First of all I advice you to study different indicators that you can find over the internet those are - Stoch RSI, MACD, RSI, WT Williams and other. I don't recommend you to buy trading courses off the internet, they don't work. Then you can try to use price predictions tools like Cryptics, now they can predict the price of the cryptocurrency for the next day with 70% accuracy rate.
Yeah try to learn about reading the price chart and it will be best to taking start with small amount of money at cheap price, after buying some coins patience is the most important because it is hard to say before investing that when you will be able to sell but in this regard we use to follow some predictions and market condition, so be ready to take risk for good trading income and dont panic just have patience soon you will earn best money out of your trading skills, use your skills dont waste your money buying indicators,.
