I guess the article is not about the restricted supplies but it means the features that #pob have are found to be similar to the bitcoin and its circulation. Nobody could predict that in 3-4 years time the price of bitcoin would touch the prices at which it is sitting. It is quite likely that even #pob would touch the same prices. The rush for buying the POB is due to the fact that it is a limited supply coin and the more you stock it in the initial days help you to make more benefits in the long term
