Hmm, again it has the potential, but it hasn’t changed the world yet.

Well, let me tell you something that might change your mind.

There are bitcoin miners in Africa, like Gridless, which help subsidize cheaper electricity for rural communities. Electricity company can sell excess energy they cannot sell to the grid for bitcoin miners. Bitcoin miners get cheap energy to mine bitcoin and profit. The locals benefit when their energy provided doesn't need to charge as big of a price for the energy. It's a win-win-win.

Bitcoin has already changed the world, and will keep doing so.
