Like every other investment/speculative asset, the vast majority are owned by a relative few.
Going forward if crypto ever took off among the general public, the general public will be royally screwed. This is because there will be a cost to using, exchanging, or acquiring bitcoin. If there is any bottleneck in the system, then the highest order "stakeholders", i.e. the guys with the most bitcoin will get to trade first and more cheaply. They will be able to use this to game the system as they can trade ahead of drops in bitcoin values and perform pump-and-dump operations at will.
