What if all the rich people come together and buy most of the BITCOINS can this lead to the control of power again in the hands of few.
Obviously that will deliver most of the power towards them. This is what happened when Roger tried to manipulate the prices of the BCH and it was made possible all because of they had lot of pumping power by using big money. Even if you had billions of dollars then you can also manipulate the prices yourself that too alone!
Who knows that they are already altogether and are the reason for current manipulations. :-)
