Trying to explain the mathematics behind BTC...?
Nothing I've seen puts it more clearly than this tweet:
If you're trying to explain the benefits of Bitcoin - of which there are many - the 21 million hard cap on the number of Bitcoin that will ever be issued is the most compelling.
Your chance to own a fraction of the world's future wealth (if all goes to plan).
Or you could hang onto your fiat cash - problem is that the denominator on the fiat system grows infinitum as the world's central banks keep on printing more of it. Not so with BTC. It's in the code.
Anyone who understands bitcoin will make life easier in the next few years.
