The real reason is other than bounty participants for the cheap prices. A total supply of 18.7 million and you can buy this cheap is just opportunity while it lasts. There isn't big exchange till today neither any significant release in development to expect quick increase. They are doing their best to deliver and then price will skyrocket.
I looked at the bounty tables, and I can say that they got a lot of tokens, compared to the total number. So at first, some participants may drop the token rate.
