And what problems are they "trying" to solve?

This is what traction looks like, sometimes it's messy. That doesn't mean it's not legitimate.

What does legitimising a currency mean anyway? It's already used as a medium of exchange and a store of value, that's legitimate.

But if you are going to try and compare it to the "legitimacy" of fiat money, you're not going to find what you're looking for.

Bitcoin is an anarchist concept, it does not seek to be legitimised. It is achieving exactly what is set out to do.

you could just see the fluctuations as the currency being honest about its value as opposed to fiat money which is just as vulnerable yet artificially stabilised (legitimised?).
