Simply because the creators want to get rich from it. As I stated above, they kept 20 billion of the 100 billion total XRP.
I thought they kept 80% for themselves?
Regardless, there are idiots that are paying 1BTC (yes USD $92) per 10,000 ripples.....
Yeah it's 80%.
100 billion XRP total, and they have kept 80 billion. Something like 1% would have been more than enough.
