In theory use, bitcoin similar to gold have a limited supply and a high demand that is ever increasing, and for bitcoin once all of the supply is limited the price is going to keep increasing, and it will become a rare thing to have, bitcoin as you said could make a change in the world, but there are people who are in their interest that bitcoin stays the way it is and falls down and perch, people who have the power lack vision and they only make decision based on their interest and not the world, but time only is capable of changing this so we have to keep supporting it.
