If in the world there are about 8 million people, each of whom will accumulate 2.625 Bitcoins in a cold wallet and never sell them, then the price of Bitcoin could skyrocket to infinity. These individuals, who have gone through natural selection and acquired 2.625 Bitcoins on the market, could unite, for example, in a religious Order, and gain the chance to change the world order. This trend is already emerging today. Pay attention to how more and more politicians and officials from different countries are being influenced by the idea of Bitcoin and becoming holders themselves.
If all holders of BTC do not sell then it is simple to think that the market is dead. There is nothing to buy after all. The market price may probably increase if the item is being hoarded making an artificial lack of supply but if there is nothing to buy in the market then it won't be long before the market becomes dead.
We must also understand that the market is governed by the law of supply and demand. Without a supply, there is no market at all.
