What moment will convince you Bitcoin is no longer a niche thing?

[gentlemand]

I still see people rolling out the old '0.00001% of the world's population own any' line which is slowly losing its validity. I'm sure it's still a small amount but there will be a point where Bitcoin fans can no longer claim to be the underdog flying under the radar.

What would that point contain to convince you that you're now part of the boring mainstream?
