This sounds like an effort to drive up the price of a given crypto product similar to how concert tickets or sporting event tickets are price manipulated. Filling all the seats (promoting a crypto coin) would create an artificial scarcity driving up prices. Initial holders, would be able to sell their holdings at greatly inflated prices, which would be similar to a tax on society, but the profit going to the initial holders.

Also, with a crypto coin, I bet the risks of significant price swings would greatly challenge people who attempted this as a retirement vehicle.
