Was ripple even around when Satoshi disappeared. If it wasn't, this isn't a really good reason why he disappeared from the scene, pretty sure he left when there was no other crypto-currency (other then BTC), and other cryptos like ETH, etc, where created a year later.
Ripple is far older than BTC. If I remember rightly it got rolling in a rather different form in 2004 or so. This makes it a double piss take as it's had 15 goddamn years to achieve something, and indeed it has - a truly ludicrous price based on nothing.
