Who would you rather trust with your money: a Batman bank or a Joker bank? There really is no right answer here. It really depends on what your investment strategy is. Sure, a Batman bank will keep it safe and guarded in the Batcave’s vault – but The Joker bank could triple your money in a matter of days. You just need to give him a shot. Be advised -- the Dark Knight claims that The Joker once burned all of the mob's money just for fun.
