the thing is, those who are trading bitcoin are not interested in taking back the power, the benefits of "bitcoin", and they don't give a crap about giving the control to "institutions" or banks,... they care about fiat and how much of it they can earn. they will never withdraw their money/bitcoins from exchanges emotionally. they will continue sticking around as long as there is profit to be made.
your title is completely irrelevant to the topic by the way!
That is a very good point. A big number of people who are currently holding BTC are more interested in the opportunity to get profit from price changes, it's just a way to make more usd or eur or whatever else
