absolutely not. No money is lost in Crisis. There are 5 money track +50/+100 tiles, which you can use to mark more than 50 ECU. See the rulebook (page 3). For example if you have 65 ECU on your pocket, you can take the +50 marker, put it under the money token and then place the both on the number 15 of the money track (50+15 = 65). I am hopping you enjoy the game!
