Very small volume is a sign that all three NXT/Ripple/MasterCoin should not be compared by market cap. Distribution model is different and the actual number of coins distributed is unknown, so counting all of them is an obvious mistake.
Very small volume ... running in PRIVATE exchanges should tell you something.
Plus you keep saying these coins like Mastercoin and NXT are innovative.
All of their claims are VAPOR WARE. NONE OF THE ADVANCED FEATURES EXIST OR WORK! Even Protoshares is a clone, it is just a funding vehicle for something that will come in the FUTURE!
YOU ARE PLACING COINS ON TOP BECAUSE THEY ARE INNOVATIVE, BUT THEY HAVE NOT IMPLEMENTED ANYTHING YET!!
You should also place iXcoin on the top of the list because... we plan on implementing the same innovation. Like Mastercoin, Protoshares and NXT, we haven't implemented it yet!
