Mining Industry

I’m trying to figure out how the bitcoin mining industry works, as Ivan says, the people who got rich in the gold rush were the ones selling the shovels, so I am trying to find information about the companies making the miners.

it seems like it has consolidated to a few companies that could give the new bitcoin miners out to their friends first? (why wouldn’t they do this, they have a limited supply and high demand)

if bitcoin becomes mine-able by only handful of companies only, doesn’t that create problems?

it seems like a huge part of the bitcoin picture i’m surprised it wasn’t in the beginner course.

oh i figured it out, profit incentive.

I just don’t know enough about how to make a miner so it seems like impossible wizardry right now
