I haven't benefitted anything from Bitcoin yet...
No, I think the very moment you converted your naira savings to Bitcoin you've already benefited from it. The benefit one can get from Bitcoin isn't just more money. That's probably what's running in the minds of the majority who get into Bitcoin, but that's not just it. Bitcoin is much more important than its fiat equivalent. It's funny but true that many of us believe and preach that Bitcoin is one way to escape the decaying fiat but the reality is that the main motive has always been to accumulate more fiat and Bitcoin is just a great tool for it.
