Think about this, the energy sector. Every product had a cost of energy, in some form, built into the price. The petro-dollar is backed by petroleum consumption. Crypto is created and maintained by energy, from any source; petroleum hydrocarbons, hydro-electric, wind, nuclear, and solar.
Imagine your crypto miner is powered by an off grid solar, and connected to the IOT via satellite.
You're "printing," storing, sending, and recieving, units of mutually agreed upon value without a middleman bank. The policies that apply to your particular crypto-currency are written and agreed to by the founder and users, versus the Fed & Congress.
Retailer acceptance and wage payment are the final hurdles before crypto subsumes the federal reserve note as the primary unit of value.
The "global warming" crowd's insistence on reducing fossil fuel usage combined with high petroleum prices is driving solar and wind which will further devalue to petro-dollar.
