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?
It is all about making a great start and a great finish. Follow the prices carefully, do your own researches, follow the news, and make your decision just according to your knowledge.
And be patience, rather than become a daily trade and it will be much better to become the long-term traders. Due to the trend of the crypto is unpredictable right now and it will be a very good decision to choose the long-term trade. Try to get the rumour about crypto and it will become a very good point to buy the crypto.
