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?
Now it is better not to trade, you need to wait for the bull market. If you trade it is worthwhile to put a stop-loss and trade for short. You can trade in a long time if you are willing to wait.
