On: Ask HN: For Bitcoin to be ubiquitous, what must happen?

I mean that I believe in the fundamental need of BTC, the potential for significant adoption and the reality that it can be simplified for all consumers. I think BTC will win out versus other crypto-currencies because its adoption thus far, which makes it hard for a secondary one to scale beyond BTC. I own and wish I doubled down earlier...

Ok but what part of it makes you believe in it, not just over other crypto, but why it's needed in general?
