Frankly I don't even think Ripple should be listed period. Somehow they just randomly change the # of coins and their marketcap goes up because of it ? How does that even work ? Would that work with other coins? I understand doubling/whatever the money supply, I just don't understand how that tripled the value of Ripple.
I explained Ripple a page ago, here's the short version just for you:
There are 100 billion XRP.
Ripple Labs held 80 billion of these and so far has given ~9 billion away.
Coinmarketcap initially reported only that ~9 billion XRP are the "available supply" (the default view, the total supply is still ~100 billion and can't increase) - now they corrected it to show ~29 billion, which is 100 billion - 71 billion held by Ripple Labs.
I am by the way not sure how this should make them "not available" (especially considering that Ripple Labs is giving them away), but that's up to Gliss to decide, apparently he chose to limit the anti-Ripple trolling around here by just deciding not to count XRP held by Ripple Labs as "available", thus reducing their market cap in the default setting and making Litecoiners happy...
