If people stop buying bitcoin, house will begin and the block system will be shaken very strongly, this will lead to a full house and everything is so panic that bitcoin falls.
It will not be boring because this will not happen so that bitcoin has disappeared, we will continue to participate in its development and it will turn out so this development will not allow it to die.
As for me, that long-term perspective affects the course of events such as investment bitcoin by bitcoin buying bitcoin. It is bitcoin and therefore it will live and prosper for a long time if we promote it.
The king of all coins has always been considered bitcoin and I do not think that someone will be able to circumvent it in the near future, another crypto currency. But the etherium makes good results and catches up with it.
