Why do the creators of ASICs not just keep them for themselves? If ASICs are able to mine BC so fast, why are the creators of these machines even selling them? If they just created them to mine with them themselves, they could get so many BC and in turn make BC worth so much (as BC for the rest of us would be so few in comparison) that they'd theoretically make a hell of a lot more money that way than by actually selling these machines.

What's the hidden agenda with sharing these machines? Do the creators of ASICs think/know that BC is a bubble/fraud and just want to make as much money as possible before people realize that their machines were BS?
I can't really answer this without speculation, since I'm not an ASIC developer myself. Please keep that in mind when you're reading this!

There are a two paths that ASIC miner manufacturers have to make a profit.


Expend fiat to produce mining equipment

Use mining equipment to mine bitcoin

Sell bitcoin for profit

Profit


Accept fiat or bitcoin in exchange for ASIC mining equipment

Profit




The shortest path to profit is to sell the device. Existing bitcoin is worth more than non-existing bitcoin right now, especially when that existing bitcoin can be turned into more mining equipment.

Keep in mind that they can also do some of both. While it may not actually be so, it's fair to believe that employees of an ASIC manufacturer are likely to invest in their own product by purchasing one.
