Bitcoin has broken 40,000, and the leading exchange ZB.com is now quoted at $33,223. This round of skyrocketing is related to more and more people paying attention to it. As more people hoard, the output of Bitcoin will decrease due to the halving. However, more and more people will use BTC, generating value in circulation. The supply-demand relationship further pushed up the currency price. This is why the price of Bitcoin will increase.
