Oh my. Hold your horses buddy. Nobody is forcing poor people to buy bitcoin. People are just faced with a choice, they can hold their value in fiat currencies that corrupt governments are printing like crazy, or they hold their value in a decentralized currency that nobody has control over and nobody can print on a whim. Just because you feel like you missed out on a good investment and so you are bitter towards an entire growing industry doesn't matter at all to people who are using it to escape corruption.
It really isn't nearly as complex or evil as you think it is. It really is just a way for people who have repeatedly been screwed over by corrupt politicians to escape corruption. It's just a matter of time until more and more people around you realize the same, and eventually you will join in, albeit a bit late due to your ignorant bitterness. You do yourself no favors by being against something simply because you don't take the time to understand it.
