Once the winter gambling boxes come, should I buy them if I have enough for over a 100?

Obviously if I had a but enough for a few I would not spend it, but as of right now I am sitting at 8.2M, well over enough for a 100, and 100 is quite a bit, would it be worth it? I am more of asking as a discussion between us rather than genuinely asking since I fancy a bit of gambling as I've never gambled in this fine game of ours.
