The amount of bitcoin is limited only around 21 million, estimates that if bitcoin has been mined, the price of bitcoin will increase. Guessing I have several factors the price of bitcoin will rise compared to today, digital currency will be widely used in the next few years, whether as a payment system or a place to gain money. And most people have known and even many people have gotten wealth from bitcoin so they will not hesitate to choose bitcoin to get money again.
We should not doubt about bitcoin because its born to increase. I admit that bitcoin is falling and the price is to much damn low as compare to last year's price. But believe me its not end of bitcoins.
