Don't be greedy, bitcoin wasn't created to make a selected few rich or make another rich instead, it was created to help the masses from the slavery the government with their centralized mode of operations have put us. It was created to clean up the currency market and used as a more of payment for the average human. We should advocate more fore the technology to go viral instead of withholding the information for our selfish gains.
In fact, witholding it will have the opposite effect. It has to be used by the people to gain value. Think of any other technology like computers, phones, cars. What value would they have if they were used only by a few people in remote, isolated parts of the world? You wouldn't want a phone or a car if you never saw anyone use it and understood the benefit of owning it.
OP doesn't understand that scarcity and availability are two different things. You can have a scarce material available in every city. A good example of this are expensive cars like Ferraris. They are expensive and scarce because they are always produced in limited numbers, but every big city has a dealership and you can also order a car online.
