Duelbits gave $1 freebets to my account, maybe also to other user accounts, but unfortunately, because I haven't opened my email or deulbits account for a few days, the freebet is no longer valid and can only be used in UFC 285 betting.
I have not checked my mail that I have registered from few days so maybe I have also received this freebet but this can be again to random users but as you said it's no longer valid so has any other player able to claim it timely?
