After reading crypto blogs, books, user experiences, and this forum over the last few months, I've come to the conclusion that Bitcoin will not become the universally accepted global currency.

It doesn't have many applications apart from storing value and it's not user-friendly.

It's not all BTC's fault. The current economic model doesn't support its widespread use because we're still dependent on centralized institutions for infrastructure.

Kind of a chicken or the egg? type question. What comes first? Decentralization or one universal cryptocurrency?

With seemingly unlimited ICO releases, (https://ethereumworldnews.com/ico-volume-double-2018/) which qualities will the be-all and end-all coin have? And which economic circumstances will facilitate its success?
