Given that it's a currency outside the command of any government or central bank, Bitcoin (CRYPTO: BTC) is inherently an outsider's challenge to the traditional financial system.

Strategy's strategy is essentially to issue convertible debt and equity to finance the purchase of billions of dollars of Bitcoin.
