I just always wonder if those billionaires still invest in btc. Do they even know btc exist?
I do think that they're aware of this bitcoin. Cause billionaire will always find way for them to become richer (greed). Once a billionaire said
People are "underestimating" bitcoin and it has "great potential left," .
It is a contradiction to your first word because at first people are greed people don't want to say it to others unless they have bought the right amount for them and before they will promote bitcoins they make sure about it. Billionaires are billionaires they have the money and power every great potential that is about to enter the market is what they focused and research its potential.
