how to get points

Wrong

No, you don't. You get points from other people's giveaways, not your owns. Just wait. :)

Yeah to the first , you do get points from other people giveaway , not from yours though, so do not need to make Giveaway to give it away

Points build up quite fast here, leave the site for a few hours and you should have enough points to eneter almost all giveaways. Also if you want to improve your odds try entering contributor giveaways (those that require you to have donated a certain value before) look for forum giveaways and puzzle giveaways. Finally, be patient, eventually you might win something. P.S. if all else fails try to win fortix
