According to ITO rules " Shares purchased using a participating coin will be sold at a 10% discount. "
How does this work?
You will be able to buy BlockNet tokens at a 10% discount with participating coins through Coingateway.net
For pricing, we'll pick prices of Blocknet tokens at the start time of the ICO based on a recent average (exact algorithm TBD). Then we'll deduct 10%, and put up a sell wall there.
Any discrepancies in price between coins will be arbitraged by traders, and so the market will converge on a 10% discount no matter what coin you use.
The value of participating currencies tracks the exchange rate of BLOCK. Any deviation up or down gives rise to arbitration opportunities between participating currencies, so their prices will all converge around their price relative to BLOCK.
