Planning is very important in trading, without any assumptions and analysis, it is very hard to make money in trading. In crypto trading, the fluctuation seems to be very high and without any planning, we are going to lose our money by predicting the market perfectly.
Nothing is easy in this world any thing if we want to use for making money needs planning so the same thing will be needed in trading and there is no issue according to me spend money with proper planning. As I get my salary then I choose specific part of my income for trading and spare the remaining for my daily needs so I never get worry and trade for long term.
in the beginning traders have no such profit from trading but when they start earning from trading then they need to utilize that earned money, as according to my strategy i have spend very less amount of money which i could afford to loss and after that i used all the money came from trading. The benefit is that if you loss all the money in trading then it will not make you panic thinking that it was my hard earned money. So I suggest you that don't always spend money on trading from some other means, just utilize the money earned from trading.
