From his arguments there are a lot of bias or his knowledge is limited. I will like to believe it's a bias instead.
Cryptocurrencies are able to do the 4 functions mentioned above and more.
Don't be surprised this guy might have a huge stake in the crypto industry.
Well, nice debunking.. I hope he sees it
Thanks. Petraeus IS biased. Biased towards centralised authority, state power, and stability.
Ironic, really, given that blockchain tech can and will be turned towards those ends sooner or later. I sense he's simply reacting to the spirit of crypto development, prioritising decentralisation, independence, and freedom from the state and bankers—everything he despises.
