So basicaly , if the cap is 100mil $ what do they do with the surplus ?
20% will be allocated to the BNT Ether Reserve, to further improve the liquidity of BNT, which increases stability while reducing conversion costs (price slippage) for all.
80% will be locked for two years in a smart contract that will buy back BNT for 0.01 ETH (the initial price) whenever it is available, according to its calculated price. The purchased BNT will be added to the Foundations long-term budget, and after a 2-year period, any remaining ETH will be allocated pro-rata according to the Use of Proceeds chart in our Token Creation Terms.
