I want to know if until when the deadlines of those promo?
About what promo you're talking? If you're about Reward points promo, here is the answer:
3x reward points (RP) promotion currently running and ends in 35h:25m:43s (6 RP/free roll, 3 RP/referral free roll, 3 RP/multiply roll).
As I know there are no other active promo on Freebitco.in now.
