The title is a little bit misleading because it implies that you won 1 BTC by gambling, while in reality you made 1 BTC as an affiliate. However, if you can convince players that easily to use your affiliate link, congrats on that!
I thought first that he won but he didn't said in the title that he won. But instead he said that he "made" 1 bitcoin for just one night. I will try this soon but I'll use social media and will endorse my referral to my friends but I don't think I can win 1 btc for just a single day or night.
