it worth nothing that in 2013 after the doge peak the altcoin section was full of malicious devs, who were running their scam-fest, consisting of many alts, like aurora/blackcoin /maxcoin/stockcoin(the first one) ecc....,
i was there for every one, and i can tells you that with the first three they have surpassed by a long shot the 340M of this news..
actually i think that with aurora only, they have scammed a monstrous amount(i remember that coin surpassed litecoin in value, when litecoin was worth about 300M+)
I'm sure whoever was involved in some of the dodgy coins made a pretty penny but market caps are meaningless. If a developer tried to cash out their premine coin with the multi million dollar market cap they might just about scrape ten to fifty grand before the most markets would fatally vapourise.
