Maybe intel need to focus more on it's CPU builds because its competitor, AMD is not slowing down at all, they just released another new Ryzen CPU with 24 Cores after the latest Ryzen 9 CPUs on the market right now.
Some gamers are making noise about this online that's how I get to know and some are dumping AMD saying of all the latest CPUs they released Intel 13th gen CPUs are way faster and better.
I think Intel stopped them because they are too niche.
Intel is in trouble right now so they need something that will sell a lot. Like a CPU or a GPU for general processing.
Bitcoin mining might end up being profitable for them, but maybe they won't be selling enough units to justify it. They are now in a situation where they have to focus, otherwise they will collapse.
