maybe what will happen if the bitcoin price keeps falling is bitcoin will not have any more enthusiasts and it is possible that the price of bitcoin can return to the price as it was in 2013 and the price is very cheap and certainly will make many people lose.
Different people think differently. Some say that it will disappear from the market and some argue that it will be the mainstream in the future no matter what will be the price. When all the people in the world start using their bitcoin they will not compare it with dollar or their local currency. Bitcoin will also be assumed like our regular local currency.
