The minimum requirement for the success of the ITO is defined as 850 BTC.
But lots of sales were not in BTC.
Synechist, could you please confirm that with the 850 BTC requirement you mean (total_number_of_BLOCKs_sold * 0.00025 > 850).
The minimum requirement includes Blocks from Bittrex , Poloniex , Bter and Coingateway(Blocks bought with participating coins)
About 1000 btc is collected as of now
