To decentralise crypto mining software that is easy to use is required.
With the cost of power many large centralised mining sites are closing, which in some ways is a good thing, as centralised is not the ethos of crypto.
Simple to use software, that everyone can run is required. But it has to be fairly simple to install & use.
And it needs to make more than it costs in power.
And it needs to be able to be throttled, so CPU's & GPU's are not running flat out which could overheat & damage them, adding to the costs.
Cudo may have ticked a few if not all of these boxes.
