The optimistic view of this is that you can run a node in a distributed payment and compute platform for a few thousands bucks. Consider the alternatives: the infrastructure running PayPal, the massive and archaic automated clearing house systems used by megabanks, whatever it is Western Union does to move money. You can participate in a distributed, open source alternative for what amounts to an affordable price for those in developed countries.

I am not claiming you should do this! What I'm attempting to illustrate is that this momentum towards freer and more open systems is what drives the technical optimism in cryptocurrencies and blockchains. There seems to be a Moore's law effect dropping the price of what is currently gatekept by governments and megacorporations. Hard work is once again creating exciting innovations that at least have the potential to improve the world.
