This article is attempting to use
argumentum ad populum in order to support Bitcoin and suggest what benefits it has, and it relies on the
bandwagon effect as a means of promoting BTC.
In the context it's actually ridiculous to even attempt to use such a fallacy, because using the logic that something is good just because it's becoming popular or is popular would mean that people should continue to use fiat.
While the conclusion
may be correct despite this, if you are trying to be persuasive and affect actual detractors of Bitcoin, you should be addressing arguments individually and directly.
Also, use a normal title next time.
