Monero is trading just over $90 with just under 15 million coins circulating while PIVX is trading just under $2 with a little under 55 million coins circulating. Based on supply it would seem that if Monero and PIVX were trading at parity its' price should be around $25. Verge has over a thousand times the max supply as Monero with a price of .001961 and if it was priced at parity with Monero it would be .091 or nearly 46 times its' current price. According to the speaker in this video Verge is the only completely private alt coin of the three we discussed here. Not financial advice, just some interesting information.
