Keeping yourself full of positivity won't help the price to go up. In fact we should accept the fact and act accordingly. Bitcoins are one of the rarest coin, so definitely today or tomorrow it's price will go up. If we see the question raised by OP then its pretty easy to answer, the Bitcoin's price will only grow when the demand of coin increases among the masses. Now many people are wandering why it will grow when demand increases ? Let me make clear to everyone that, Bitcoins are limited in number, this means no more Bitcoins can be created, so this make Bitcoins valuable. Now when the demand of the coin increases, the price will also increase in order to meet the demand of the people.
