My main usage for Bitcoin is a sense of security

TL;DR Bitcoin is already adopted by the highest influencing humans, the rich.

I don't know if Bitcoin will ever be widely used as a currency for day to day purchases. But I don't think it's important for it's survival at all.

I think it is fulfilling a critically important rule as a way to secure tradable assets without having to trust anyone but yourself. this was never possible in the history of the world. as a wealthy man, you always had to trust someone or keep some big vault. now all you need is to remember some words.

If you are a rich man today on this earth with minimal sense, you own some bitcoins, purely to secure yourself against the unknown, doesn't matter if you know anything about it, when you're rich enough, you'll own bitcoin. If this is true, it then follows every rich man on earth as the wish and heart desire for Bitcoin to survive. Those rich men, rather you like it or not, are the most influencing individuals on the planet.
