50 Millions, are you sure? We get 10000 SNT for 1 ETH, so the crowdsale is over after 5000 ETH?
if this gets widespread interest, then expect the same issue as Bancor ICO;
MEW nodes crashing, purchases hung pending, followed by cancelled tx and money returned a few hours after ICO closes, with loss of fee.
an ICO team get rich, while stating you lost out because their network suffered 'massive attacks'
and no one in the US is welcome to join it... because they might sue them.
