Even than if it worked, I would find these kind of miners with usb-c highly dangerous. People, who doesn't know much about electricity or doesn't make some research in this topic can easily burn their homes down only by plugging a usb-c miner in a hub and letting it behind running without any super active cooling.

I'm not saying usb-c would be a dead end or would be bad, I only find it risky and a bit too dangerous. That's why I reckon usb-a miners are enough. Who knows what kind of super-chips the future and the developer misterminds bring us.
