In the article, you said it can't hit $1 million per Bitcoin. I'd argue that it can, and will. It may not 100X or 1000X but going from $60K-->$1M can make a significant difference in many people's lives.
I see your argument about me mentioning $3T companies. That would only be a 3X from where Bitcoin is at. However, Bitcoin can and should easily overtake gold.
I think you are improperly identifying that people only see Bitcoin as a vehicle for getting rich. I view it as a way to keep from getting poor. As soon as more people realize this, the price can move exponentially.
As far as understanding what you can do with Bitcoin, there are countless resources online where you can educate yourself about the benefits of Bitcoin and why it makes sense for everyone to own some.
