Ok. Less text and more pictures

It is pretty amazing how our infrastructure has grown. I hadn't seen either of these before, and they make me confident in the security of bitcoin and proud of what we've accomplished.
These are just two examples of ambitious groups who want to earn income by mining bitcoin. They have large amounts of capital
at risk and a vested interest in securing our network. They are rewarded objectively based on how much work they accomplish.
I've seen these pictures, and have a same feeling as you looking at them: these are the people that will protect the bitcoin mining at any cost, not destroy it. I think they would go as far as restricting their own network hashing percentage, if the unlikely event that would be necessary. However, as time passes by they will have trouble keeping their < 10% of the hashrate, chances they can afford to continue investing and grow the percentage are slim, they have to cover the cost of investment sooner or later.
