I think there will be many models in consumer mining. There will of course be hosting solutions (though these can easily be or become malicious). There will be solutions like Bitaxe - which are very expensive in terms of $/Th but the philosophical benefit is that bitaxe is open source. Then there are the solutions that Canaan has made (branded as small space heaters that mine Bitcoin), these presently give the best $/Th but they are certainly not open source. I expect more companies to come out with similar products as it gives an opportunity to resell very old chips at WILD margins relative to what the industrial industry can accept. The risk for this segment in a vacuum is that it never becomes more than a hobbyist niche (where buyers are not strictly concerned with rationality of profit). However, this is where opportunities arise to really lean into the “heater that mines bitcoin” for things like water heaters and the heating element in home HVAC systems.
I’m running a Bitaxe and 3 Canaan Avalon Nano3 (with 3 Nano 3S on the way in Feb). I’m having fun with this, but it’s certainly not profitable at my present assumed power costs.
