The largest was the corporate or big miner. Easily found and targetable by government and competitors. Large physicals building with major power draw. Specialty buildings with dedicated power, rack space, much of the infrastructure is special purpose. Very difficult to move. If trying to change jurisdictions, it takes months or years to build a new facility and the appropriate utility upgrades.

The smallest are the home or solo miners. Extremely agile. Very difficult to stop or even find. Could run off a generator in a garage. If there is regulatory crackdown or seizure, these miners can be tossed in the backseat and moved across the country with almost no effort. No special power hookups, these miners can be back online almost instantly. The cypherpunks will keep this class going regardless of the expense or other cost.

Mustangs were the middle, maybe a shipping container or two. At most a small building, but that would be pushing it.
Big enough to have a noticeable impact when considered as a group. Small enough to be individually relocated. Often able to mine on stranded energy. Small enough that they would be difficult for regulators to find. The backbone of anti-censorship. This class could possibly exist in larger numbers in hostile environments. Simple to transport the container to an old factory or somewhere with commercial or industrial power, hook it up, and successfully back online. This class can be abundant enough that if one is targeted, the others will continue without impact to the system at large.
