What do you mean by "There is no such gevaway at this moment"? Did you not see the twitter link posted by aysg76?
All you have to do is follow, like and retweet, tag 2 friends, and comment your Roobet username, and Roobet will award 5 lucky winners with $500 each.
Actually you didn't read it carefully and i have posted
there are no such giveaways in response to @UserU in which he was mentioning that when you don't have 2 friends to tag on Twitter for this giveaway.So i said there are no such giveaways at the moment in which you just retweet and get a chance to win $500 if you are lucky.
But still many people have opted for this opportunity and you would find lot of participants in this pure luck based giveaways.
