I have made and lost fortunes on BattleBeast Dragons.   250 Lindens =$1.00 US  this is subject to fluctuation.  I sold 2 ancient dragons 1 night  one for 15,000L and the other for 19,000L that is 34,000L minus a 10% cut to the auction house.  Now tell me how much money that would be in dollars…   This is a lesson on Micro Economics.
