Re: Why don't the companies making the mining rigs just use them instead of selling?
Simple really. Why on earth would any company sell a mining rig when it's that profitable and they could just sit there and mine for a few months with them, make all their money back, then sell the chips??
If they wait too long while mining, their chips will be sold for much less because difficulty is still rising.
The only solution to this problem is preorder model and delay delivery
