Hardware mining for calculating "very specific input describing (blockchain)"=>"RFC.SSL.Wasting time" it is wasting time for me.

I want to use hardware as helpful tool in finding quality data results.

So. ASIC's work without memory ? ASIC's work without floating points calculations ?

So. ASIC it is black box in airplanes ?

PS: Hardware mining it is very expensive for me. Captcha mining most profitable for me.
PPS: Captcha mining it is expensive too, cause many things like this: - "Invalid captcha. Try again."
