Interesting article Silvi. Similar to Ed, I see a negative feedback loop limiting the potential for strong adoption. Cryptos are fundamentally volatile, and therefore useful as a speculative asset but not as a medium of exchange. Whenever bitcoin gains any traction in commercial use (besides tax evasion, money laundering, and purchasing illicit substances) the price shoots up and it becomes more volatile, thus limiting its commercial applicability.
As a FB shareholder, I am really excited about the potential for Libra (or "Diem"). By taking the best features of a private blockchain and public blockchain, I think they can scale into success and overcome the aforementioned negative feedback loop.
