StarStreet was a smaller but growing fantasy sports site that offered something a bit different for fantasy players. They offered a Wall St. style market where each player had 200 shares that were traded on their marketplace. Your job was to buy low, sell high. The better a player did the more their stock rose and vice versa.
It will be interesting to see how the stock trading style of fantasy will be handled during this transition. I would be surprised if DraftKings brought over that piece of business and offered it as a new type of fantasy contest.
