I have no clue but who do, I guess Investors, thought, who get bonuses in first week of crowdsale, they're panic when the bounty hunters will recieved their rewards even just 20%, may be investors think the price will be low than now when distribution will be made then they just bought more EDG at the time. Just my opinions, correct me if im wrong

yes same happened with chronobank. but it seems that price will be not cheaper when bounty distribution happen
just look at
https://liqui.io/#/exchange/TIME_BTC. they sold it for 50% and now regretting it
