< (2 of 5) Next argument >
Metcalf’s law dictates that the value of a network is dependent on the number of users in that network.
A telephone is worthless if only one person has one. It has very limited use if only two people have one. But if everyone in the world has a telephone, then the network becomes valuable. The same applies to Bitcoin. As more users buy Bitcoin and use it as both a currency and store of value, the utility of Bitcoin increases. 94% of Bitcoin’s increase in value since 2014 can be directly attributed to the principles of Metcalf’s law and the expansion in user volume. Therefore, providing the number of users continues to increase, Bitcoin will remain a prominent and desirable currency.
Bitcoin use is not increasing. It peaked when the cryptocurrency bubble was in full swing in 2017. However, now, the number of people using Bitcoin, both as a liquid currency and investment tool, is plateauing at best, and decreasing in some cases. Many retailers that used to offer Bitcoin as a payment option have since abandoned the idea. Of those that kept it, a large portion report that almost nobody uses the currency. 
[P1] The value of a network increases as the number of users increases. [P2] The number of users of Bitcoin is increasing. [P3] Therefore, the value of Bitcoin continues to increase.
Rejecting the premises
