EV question for Money Casino

[sorry4me]

I am trying to decide if this site is worth it: http://www.money-casino.com

They do not have a normal wager requirement, instead everytime you place a losing bet 1/15 of the loss is withdrawn from your bonus account until it is empty. All bets and wins are placed in your cash account.

I'm wondering if this 100% bonus of up to $100 is worth it but I need someone with better math and gaming theory skills to evaluate the EV. Thanks
