I understand that this is the perception (in the outside world), but you have an inflating currency at something like 250% from what I read. If you keep price steady and you also get 200% up on your SPs, then ...you triple your money.
So the system is designed in a way where we don't get 90% of the inflation rate for fun. It is because it is expected the price will drop. Whale investors may create upward spikes for short periods but this is not the normal.
