In order for bitcoin to "win" it needs to get massively more valuable. Valuable enough to move the equivalent of trillions of dollars per year and users need to be able to make million dollar purchases without drastically changing it's price. Otherwise it will never be truly useful as a currency and as interest is lost and prices go down parties concerned with verifying the blockchain will become sparse and the whole system collapses, magical blockchain and all.

Bitcoin has far from "won" in the sense of a currency and if another crypto-currency surpasses it's current popularity the faith in any crypto-currency being stable enough to move trillions of dollars each year is irreparably harmed.

People raising a few thousand dollars here and there in other crypto currencies is fun but it's not only paltry and not generally useful but can easily be attributed to entertainment more than economics. Once the novelty wears off, where will crypto currency stand. That's the most important question we need to ask ourselves. All these alt-coins aren't evidence of a thriving eco-system, they're evidence of the very reason why a cryptography based currency is inherently valueless.

The blockchain cannot last without bitcoin becoming massively more valuable. Many people already see bitcoin as being too valuable and alternatives too easy to create. What needs to be done to scale crypto-currency to the level of an actual currency? Government backing?
