I'm not trolling, and I can't tell why you would think I was. If Rolls Royce made a car that was popular that they ended up buying out some part that they used, I'd say that they popularized use of that part. (Your comparison doesn't work because RR constrains supply rather than enlarging demand.) While GPGPU existed before cryptocurrencies started using it, it was a niche thing of minor interest to scientific computing and a little bit of general "that looks kind of neat if we could get it to work for anything useful" from the rest of the field. Then someone said, "hey, you could offload crypto mining to a GPU and use GPGPU to actually directly make money", and overnight it exploded. One might even say that GPGPU became, say, popular.
At this point, the only explanation I can think of is that we're using different definitions of "popularize" (I'm using "To make popular; to make suitable or acceptable to the common people; to make generally known."), or you don't know what GPGPU is (I'm using "General-purpose computing on graphics processing units").
EDIT: Added that RR limits supply rather than raising demand, so not the same thing.
The very opposite: it made GPUs and many other components more expensive.
