No argue there, that is not what I tried to convey. I simply explain that the hash rate continues to increase over time and therefore, you can assume that mining adoption keeps increasing and therefore it is profitable in many countries. To the best of my knowledge, there is no way to know how many solo miners are out there exactly, even the number of nodes reported does not include the ones running over TOR, which are many, specially since Umbrel OS and Start9 appeared in the picture 

Thanks for the tip about [Stratumv2](https://stratumprotocol.org/)!, definitely worth looking into, checking the web site and reading that Matt Corallo is one of the collaborators speaks tons to me.

Are Bitcoin Mining Pools a Threat? 

>Is Solo Mining it worth it? In few words, if it wasn't, there would not be so many miners across the world, evidence of it is the hash rate continue to increase

The hashrate isn't an indicator of solo mining, just mining in general. Pools increase the hashrate as well.

Have you looked into stratumv2? There's an improvement spec'd out that would help combat centralization with job negotiation. There's still room for improvement but I don't think mining pools are going anywhere
