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 required funds includes the value of altcoins used.
Their value in BTC is calculated at the price they were traded at.
