Bitcoin is human's first and best attempt at creating digital money, it is money that is designed to deflate instead of inflate, it is also the most secure form of money ever created and powered by the biggest compute power that ever existed.

Bitcoin is unstoppable, due to its decentralization, it is bank and government resistant.

Bitcoin is also transnational money, that exists everywhere, owning Bitcoin would only require memorizing a few secret words.

A low  time preference look at Bitcoin's price movement and due to the continuous exponential adoption of the technology, it won't be so hard to realize that Bitcoin's value will only increase further on the long run.
