That isn't correct. If the ASIc manufacturer produce them for X can use them directly and it only costs Y to operate them for Z profit. Then you can price them as Z-Y-profit_margin > X. The lower the operating cost, the higher your profit margin per chip if you sell it. Selling the chip might have a 50% profit margin and mining has a 10% profit margin. If you wanted to get into mining you would build a holding company owning both types of companies.
