This proves that marketing campaign on Bitcointalk works very well and users of this forum play and bet on 1xBit.
This is utter nonsense and there is no evidence to support your claims. There is not one bitcointalk member who would believe the lies you are spreading here and risk their money on a scam platform like 1xbit / 1xbet.
The failure of their contest in the "Games and rounds" section is evidence of this.
Of course you don't have to take my word for it. I just draw logical conclusions. If someone have campaign on Bitcointalk for several months, knows the possibilities. So since it launches the second campaign, it means that the effects of the first one are at least satisfactory. This is purely for Bitcointalk users, so it's clear who makes the campaign profitable.
Why contest in the "Games and rounds" section fail?
