Miners are incentivized to drive their energy costs down as much as possible. The most viable ones will be net energy producers since their the marginal cost of energy to power their rigs is zero. Therefore you’ll see the mining industry merge with the global energy industry.

As bigger players come into the scene and the cost of going to space drops dramatically, then it’s a matter of time before governments start mining in space as a matter of national security. They’d deploy mining rigs in orbit as they’ll have limitless and mostly unobstructed sunlight at all times and there’s limited physical access to the hardware.

In the far distant future this could turn into an arms race to capture more solar energy as it’s far more abundant than any other source by far. Could bitcoin get us a Dyson Sphere? https://en.wikipedia.org/wiki/Dyson_sphere
