Why Cryptocurrency is better than fiat currency?

[Aya]

Note: Some of these factors doesn't apply to every single cryptocurrency out there, especially the "secure" part. Sure it applies with bitcoin, but definitely not with every single one. Especially with the lesser known projects, I'm going to bet that if developers tried to inspect the code of those projects, chances are, there's going to be vulnerabilities(ranging from mild to sort of the more 'deadly' vulnerabilities"). It'd be more accurate if you named this "Why bitcoin is better than fiat currency?"

I agree with what you are saying. Although Bitcoin has a lot of advantages, fiat currency still has its own edge over cryptocurrency. And indeed, not every digital coin has a strong security system.
