I just cannot see this "mining getting in crowds" happening. Whenever I talk about mining to anyone, they just see it like some kind of next level pyramid scheme .
The people just really don't want to put money in something they don't understand. An average human from a random street cannot figure out what to do if you give him/her components to build a fully operational 6 GPU mining rig.

Also, median pay is just too little in some countries to really save up/risk for mining rigs and also try to keep your family well fed.
