They're playing musical chairs right before the implosion. Ripple might be worth a couple billion dollars as a dangerous speculation. PayPal, an actual, real, live, huge, global, payment & money transfer system, is worth $92 billion.
Some people say you can't place a value on something like Ripple. Sure you can, treat it as an actual business, measure its prospects over the next 3, 5, 10 years. What are those business prospects for the next few years? Not much, less than that of Square and Stripe.
Ripple is just this bubble's CMGI or Internet Capital Group. Bitcoin is this bubble's Cisco or AOL (if it's lucky). The junk ICOs are DrKoop.com or TheGlobe. There's nothing unique about what's going on, history is rhyming as it so often does. It's a likely indication the global liquidity asset bubble party - spurred on by so many central banks pumping crazy levels of liquidity into the global economy for a decade - is reaching toward a climax, again.

Granted, enough people bought into the flawed logical to see it happen a couple times over, not realizing that there's no reason for XRP's existence.
