Just imagine, that a fraction of Bitcoin is owned by every human in the world. Let's assume that there are 8,000,000,000 people in the world. And 21quadrillion of units in one BTC. We get 0.00262500 BTC for every human. that's 11 bucks now. Not fun. Let's elevate it to $1K. It means a hundred-times growth approximately. So, $500,000 for 1 BTC. Sounds like a good deal?
P. S. I'm not an economist. Don't take it as investment advice.
