The analogy I like is that traditional currencies work in the same way, the money supply is the 10,000 coins and the central bank represents the 99 people and has the 1,000,000 coins. (In practice they have an infinite amount but whatever) In traiditional currency systems the central back adds more money to the supply by buying financial products In your scenario the 99 people add currency to the money supply by buying whatever they opt to buy. The differences are that the central backs can print as much currency as they want rather than being limited to what they bought earlier and that it's many people vs one institution with some mandate to keep the currency and economy stable. That said, if I was one of those 99 I would be careful and probably collude with the other 98, if I tried to cash out too fast I would collapse the value of bitcoin and the rest of my investment would be rendered valueless. So they do have an implicit motivation to preserve stability.
