So basically, don't expect to win in a give away contest like this.
What's wrong if anyone wants to be a winner of the giveaway? We know it depends on luck but we try our luck and usually, we want to be a winner of that. Though it is not easy to be a winner of the giveaway yet we usually expect to be the winner of the giveaway.
There are many people who have been not lucky in these giveaways so have a mindset that it's no fun in taking part in them but we need to realise we are not placing any bet so why we worry so much about it? You take part and rest depends on luck but if you are not interested simply leave them.
