Idk, if BitShare is actually Bitshares AGS and Protshares merged (4M in total thus) I would say it would be worth what that bitshare respesent.
I readed before they wanted to implent bGold, where one bGold would be worth 1 oZ of gold if it would follow the market price.
Therefore its hard to say, but I think I will supprass litecoin because of divident system and there will be only 4M in existance instead of 25M (if correct, again).
