I agree with you. The 20x wagering requirement is more than fair, to be honest.
It’s free money after all that you can win just by retweeting a post and posting your Bitz ID! No deposit or anything like that is needed.
So, nothing to lose. If you manage to fulfill the wagering requirement and end up with some profit, then good for you. If not, then at least you enjoyed playing and placing bets for free.
Giving the number of retweets so far, the chances of being among the winners for anyone who participates in this promotion seem really good!
It is not impossible to withdrawal with a 20x wagering requirement. If the user is extremely lucky, he can do it.
If he is not lucky, at least he played lots of games and tested the platform. Which is the goal of such promotions and giveaways
