Right social media has opportunities from gambling platforms but not big one's and most of the time actual players avoid them due to bot problems but like to play games and gain with it which is also nice strategy for those who don't want to waste time on social media promotions.
It’s really a waste of time if you will participate and spend your time waiting on the result. The typical requirements of social media contest or giveaway is just like and retweet. It only consume few seconds of our time and that’s negligible if you are randomly browsing on twitter.
I know most of the times or say almost we don't stand a single chance in these Twitter giveaways but I won't consider it as waste of time because it hardly takes few seconds if you are active on twitter for them or checking for any updates so it's our wish that whether we want to take part or not.
I think that this is what really matters, because here what is done is simple tasks, there is not so much to do, and a player does not have the patience to make tweets, to respond, at most once in a while, but Not like that, so a Like, and a RT doesn't cost anything, also if it's to win a contest, a message or a comment is also something that helps a lot and anyone can do it, personally I think that contests on twitter are The best ones, you just have to try to put the correct Hashtag and that's it, there is nothing else, that is what I think because I have participated in many campaigns and that is something worthwhile.
