Speculation: There will be XMR billionaires by the end of next year. Wrap your hear around THAT one.
I wouldnt go that far. I mean even if it quadrupled in price (hitting 600$) then in order for somebody to be a billionaire then theyd need to be holding 250 million dollars worth of Monero. Even if it went 1 thousand times you'd still need a million worth of XMR to become a billionaire.
The math is not complicated. 400K XMR @ $2500 and there you go. or 200K @ $5000. Manipulate at will. 16 month window, Say 5X BTC increase, and 5X XMR:BTC increase, or some combination (would put XMR ~$3500). We just had a 2X in 8 hours, and 3X in a week in XMR. BTC is up about 5X in the last 8 months. Is that a lot? Yeah, it sure is. Hardly unprecedented though.
