Not sure if it's really a daily giveaway, probably depends on thier mood. You may find some giveaways are not USDT but Hpoint or Hash. It's not really that huge but think of it as free spin which is worth trying for a jackpot.
Before the suspension of our Twitter account, we were doing daily giveaways on Twitter! For now we try to make daily drops on website, until we'll get our Twitter account recovered and operating!
