for example i trade with 500$ after some days that particular coin raise up my 500$ turn to 600$ i can use 400$ to invest and use the other for home purposes but i think it can work if only the coin have a good value but when the coin worth nothing your 500$ might come down to 200$ that's the risk in trading sso please is this decision of mine good or bad?
Here's my suggestion about that, you can try to use your $500 to trade and after you have been getting decent profit and it's much better for you to get back your initial investment fund and then try to use your profit to do another trade or investing in the coin. this will be minimize your own risk rather than betting all of your amounts. your idea looks so bad for me.
