Here's a perhaps unique problem that cryptocurrency solves - trustless, decentralised proof of ownership (digital or physical) through NFTs.

This is a less talking about area of cryptocurrencies but in my opinion quite an important one. For the first time we can create digital scarcity without relying on a trusted party. NFTs have no digital analogue.

There’s lots of cool problems that crypto solves, but only once speculation goes away.

I think the incentives of new users greatly increasing wealth of early users is too alluring to overcome. Until that gets solved, I think it’s hard to actually meet some of these use cases because they get crowded out by various approaches who only care about attracting investors and speculators.
