First rules of the game; Put in what you can afford to lose in case things don't go as planned. Crypto markets are so unpredictable and very volatile, You can make a lot of profit or lose it in a very short time frame.
If I were you I would keep with the small amount until I master and get used to the movements of the markets. I personally Lost slightly over 10 ETH when I was learning futures trading

but my profit-making got better with time.
Ye, you are correct mate I support your answer very well. Because if anyone can't afford to lose anything they are suitable to stay here for long because everything will just turn into nothing but waste garbage. However, when I do trade in the actual market I always make sure before at the end of the day I get profit.
