If you want stability, where you don't want your money to grow but just the way it is, then stick to stablecoins. If you want short-term profit, then Bitcoin is not what you need. If you have money you want to use in a short while, and you don't want to take risks with it, then there is no need to convert it from fiat to bitcoin. You can leave it in fiat or convert it to a stable coin. Not like the stable coin is "stable", but compared to our naira, it is.
Bitcoin is for the long term. This doesn't mean you can't make a profit from Bitcoin in the short term, but it's usually not much. We've seen over the years that the price of bitcoin gets to over a long time is way higher than it does in the short term.
The question is Do you think Bitcoin will ever become stable enough to truly act as a reliable protection against inflation?
For Inflation to affect your savings, that means you've saved it for quite a long time, a year or two or more. So if we're using that time to determine, then as of right now, Bitcoin is stable enough to be a reliable protection.
Inflation doesn't just happen overnight. The value of a currency doesn't fall overnight; it declines gradually. So which do you think is better? Not keep your savings in bitcoin because it's too volatile, or keep your money in naira for over a year and watch it depreciate?
