Why Build on Bitcoin?

Bitcoin is the best digital store of value ever created - a borderless, censorship resistant, secure, transparent asset that requires no trusted third parties. More than 10 years after it's creation, Bitcoin is still here -- and growing stronger every day. Bitcoin's economic policies are set in code and the social contract of all bitcoin users.

Bitcoin Price Since Inception (Log Scale)

Bitcoin is a trusted store of value because it is difficult to change. Protocol changes require consensus from the developer community, miners, the business ecosystem, and users.
