When you take seriously the “Be your own bank!” slogan. The basic idea or philosophy behind Bitcoin is the self-sovereignty. Don’t trust any custodian in your finance, but store your money, without permission of holding, transacting, saving. Lately, the market cap of BTC had left behind the 600 billion USD level, which’s bigger than Visa, for example.
The speculation started soon, which big company will be the next on the “trophy-list”. But Bitcoin isn’t a company or investment service. Bitcoin is an accounting system, a money-system. The competition, where it has to prove, the sector of international banking. And there is already Bitcoin is the biggest player.
