because Ripple is centralized, and it's closed source.
Will you stop, when Ripple is open-sourced, and more independent servers show up?
Considering they have handed out 100 BILLION ripples as free gifts to developers and investors that they are free to dump on N00bs heads at any point.. hell no. It was, is and will always be a scam to convert worthless 'service currency' to BTC.
So do you think that is how they pitched it to their investors? Their entire business model relies on dumping billions of made up "coins" to naive forum-goers in exchange for bitcoins? I'm not sure I understand how that could work. How does one just dump tens of billions of XRP into a market with only a few million to a few billion in circulation? Somebody has to buy them, after all. It doesn't seem like there are enough "N00bs" out there buying XRP to make it worthwhile. There are very large corporations investing in OpenCoin. The potential returns would have to be fairly sizable to attract such investors.
