I'm honestly more optimistic about cryptocurrency as a mechanism of exchange rather than an asset. As a mechanism of exchange, cryptocurrency has some actually novel properties like distributed consensus that could be useful in certain cases. But an asset class which has zero backing value seems unworkable except for wild speculation and scams. Unfortunately the incentives around most cryptocurrencies (and maybe fundamental to cryptocurrency as an idea) greatly emphasize the asset aspects, and it's getting to be long enough since it became a thing that I'm starting to become skeptical cryptocurrency will be a real medium of exchange outside of illegal activities and maybe a few other niche cases.
