1 million Naira is about $650 and if you're to use that in trading after you have gotten the required knowledge needed to do very well in trading then you can easily turn that into a big amount. You can also invest that amount into Bitcoin and in the next 10 years, you should be having more than $6500 if Bitcoin was to do a 10x from the current price. Everything is possible when investing in Bitcoin with trading or hodling but it all depends on you the investor and the time you want your profits to come. Don't say quick because that's not always a good investment. Quality investments takes time to generate better profits therefore I'll recommend you invest and wait.
No matter how good one is with trading, they cannot be winning their trade all the time and be making sure of profit, so while talking about how much that the $650 can be raised to, we should also add the possibility of also losing that amount. I prefer to do the second option, which is to buy and hold bitcoin for as long as 10 years, which will take a lot of determination before that one can happen, but it's much more with lesser risk than trading.
While I assessed these two options, if OP is really aiming to experience trading, then let him trade but not the whole amount of 1 million Naira, but maybe 1/4 of it so that he can really assess on his own if trading will work for him. If not, then proceed to investing, that’s simple as that.
We all have different points of view about this, but for me, in order to maximize the future outcomes, then we have to seriously prepare for it. Trading is highly risky, so you have to learn proper risk management first before proceeding into trading.
