$197 should be around 315k for naira under 1600 per dollar. Starting a POS business or to d sell food stuffs no be bad idea. Investing in Bitcoin or any other top altcoin to hodl no go be the best idea as per now cos em still need time to hodl am for like months before em go think of selling towards the bull run. For the time being, em need something doing to fall back at, because the money wey em father give am na to start a business, instead he decides to trade than investing about half of the money given to him to invest in Bitcoin and top altcoin, use the remaining half money(1 million) to start a business. That's even better that way than desiring for quick money for crypto via trading.
Many newbies are joining crypto trading because they think it's the fastest way of making quick cash, but funny enough that it's not because it's a 50/50 thing. You might gain or you might lose. However, the chases of losing is more than winning. To me trading is like a gamble because profits is not guaranteed just like winning in gambling is not also guaranteed.
The important lesson a newbie to crypto trading (Bitcoin) should know is that it's never advisable to trade with emotions.
Now what I would suggest the dude to do it starting a POS business because it's another method of making some little money daily. Without working the guy can not invest on Bitcoin for a long run. At least if he can be investing 10k on Bitcoin weekly he can meet up within 4 years of investing.
