The question is will 1 Million naira make good results in btc trades now, or investment of btc?
Trading is a good business if you have mastered the skill and with it, you will make far more than you can earn from holding the money in Bitcoin investment. However, considering the risk of trading which is the risk of losing all your money, I will go with investing that money and holding it because I'm sure that in few years from now, the money would have increased.
If you mean business like taking it as a source of profits in order to survive, then you are making a terrible mistake. Even with your skill, trading 1 Million is risky. The 1 Million Naira mentioned by OP is only sum of $600, traders are losing millions and thousands of dollars worth more $600.
Trading is a side hustle, don't see it as a business or a job. If OP is not dependent on the profits from his capital, best to invest in Bitcoin.
