proven scam threads like bitzure or vegacoin...
BTW, that wallet address I previously mentioned at the top of the rich list appears to be routinely divesting itself of large portions of coins these past days. It has gone from 13.5 million a day or so ago to 11 million. Just something to take into account when considering how much attention you should be paying to market activity.
That's most likely the cryptopias wallet... This address appeared at the same time they announced they setted up setup the final withdraw wallet, and there was more than 18 millions coins on the first day. As cryptopias was the first exchange where sigt was listed (and the biggest until Yobit), and given the fact on the first month the volume of sigt was 100-800 btc/day, a such amount is not a surprise.
