I think you have to learn how you can maximize your money while trading so you have to learn about candle charts or how to read charts, how to decide what price we should sell or buy depending on the history of the market or judge your decision while understanding the real demand and supply in certain crypto currency markets, the more you trade the more experience you will accumulate and the more profits you get so do not hesitate to make mistakes.
I do not get you, it's just simple math even you've taught in your math class.
