Bitcoin (as an investment) is a pyramid scheme. It produces no wealth but has become a powerful means of transferring wealth to the upper layers of the pyramid by growing through the base of the pyramid and recruiting the "greater fools" still out there. It was meant as a currency but has become a investment goal and thus a pyramid scheme. Lets get rid of it, not least for the sake of environment.
