" 1,000 ETH will be used to
purchase ICN in a 90 day
period starting from 1st of
April 2017."
Now you do the calculation how many ICN can be bought with 1000 ETH at current market price.
ICONOMI will buyback ICN on weekly basis over a period of 90 days
So, 1000 ETH per every week or per 90 days?
1000ETH per 90days this time. Next 90 days might be a bigger volume. Always depends on profits made
