There is equal chance that Bitcoins can go up, or will come down. Basically you need to understand when the price fluctuates or what events cause price to move up or down. Unlike any other asset, Bitcoins follow demand and supply policy. Both are inversely proportional to each other. We know Bitcoins are limited in number hence when the demand to acquire it increases, the price goes up. The reverse also happens when demand decreases and price goes down. Currently if we see the market, then hitting 25k is very difficult. We can expect 35k usd in the next few months.
