I think it helps to define target markets and work around that. One example was iPhone and narrowing smart phone adoption to working class execs globally as the cool thing to have as they would be the easiest to adopt. Then the sales team hit local distribution and created global adoption.

If your target market is Cassie then it’s best to understand the region, age group, purchasing power, her commodity use cases etc and build around that. It’s gonna start small before it grows big and erupts.

This is a simplified diagram, one very old book called crossing the chasm by Geoffrey Moore - the early stage to mainstream is gonna be hard. Most startups fail here and mostly because lack of funds and market needs. I think Jack might be able give some tips on how they build Twitter early stages and grew it - I think he revived it a couple of times through various strategies during the early years

But working around those target markets and creating use cases for Bitcoin will be a possible way for global adoption
