Can Ripple reach $100? Yes. But the entire crypto market cap would have to be in the double digit trillions. And until then, this is just a dream rooted in a lack of understanding the market. And this applies to all coins. Tron reaching $1 is far tougher than ADex hitting $10. Tron at it's peak was #5 at .42 cents with an MCAP of $16 Billion. You simply run out of room.
if Bitcoin goes to $40,000, the dollar value of everything increases without the market cap doing so. But for those new to this concept, lets leave that to another conversation.
