Ripples (XRP) and Infinitecoin (IFC) have almost the same high amount of coins ~91 billion IFC and ~100 billion XRP
Infinitecoin IFC (decentralized, scrypt-based mining proof-of-work algorithm ,free, open-source software, Miners are currently awarded with 262,144 new infinitecoins per block, an amount which gets halved roughly every month (every 86,400 blocks).
The Infinitecoin network is therefore scheduled to produce a total about 90,600 millions coins)
Ripples XRP (no mining - all coins available at start 80% foundation, and 20% develeopers. centralized, not opensource, 100 billion coins premined)
so what is the better coin? time will tell
