Because it would be the network all our banks might use? As in... we will have no choice in the future...
Ripple is coming after banks.
Also, if you're comparing the Ripple network with Paypal or Neteller, then it's clear that you have not done your research. Imagine if all the major crypto exchanges become Ripple gateways, we would have one SUPER EXCHANGE in Ripple. You hear that? SUPER MEGA EXCHANGE. If you thought moving crypto from point A to point B was easy... Ripple will make it easier. Assuming all exchanges are Ripple gateways that is....
Banks are give xrp's for free by the millions with a clause that they cant sell before a certain time in lieu to state publicly that they use the
Ripple network, not xrp's.
The fast majority of "available" coin have this clause attached including jebs 10 billion stash.
99% of times no xrp is needed you go straight from fiat to bitcoin or whatever you want to change (frequent flyer points, phone credit,.....) Only in the most extreme circumstances will you need a xrp (exchanging you cats tail with a square hose shoe......)
Lastly if a Bank closes up shop or Ripple is the same thing your stuffed. All is gone, totally different to bitcoin as long as you dont have your bitcoins on an exchange and it closes up. You might as well keep your fiat, banks are far safer than some company you deal with over the net, most likely in a foreign land.
The current price is mega inflated, if not banks would buy like crazy instead of waiting its time to dump.
Educate yourself before trowing away money.
