^ Nah, it is impossible to abuse the faucet or giveaways. Because there is a minimum amount before you can withdraw your earning even that is from faucet or giveaways that luckybit recently has giving 0.0005 BTC to test their site. This is my personal experience to them, I received giveaway to try their site, from 0.0005 BTC it becomes 0.002 BTC after how many times wagering in Plinko. But when I trying to withdraw there is notification pop up on my screen that I need to have a deposit transaction first before I can able to have a withdrawal option. Nevertheless, this kind of feature will never abuse by abusers.
A couple of days ago i was thinking in that feature, users need to make a depo before the withdrawal. since the min withdrawal is 0.002 you already have the balance for it, so you could do a small depo and take out the profit.
Remember that you will get a confirmation mail for the withdrawal, that's why is important to use a ream mail when you open an account.
Nice to see some users multiply the sign up token price.
By the way, yesterday i had a nice run and i want to share it:
Feels great to have a nice win on red back to back.
