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.
I've heard somewhere in the news that wall street is interested in increasing the number of Bitcoin from 21 million. In this regard they have asked professionals to make it possible because 21 million will not be enough to meet the requirement in the future. Visionary people have the idea about the role of Bitcoin in the economy in the future. Based on this we can say that many people will get more chances to earn money with Bitcoin.
