Hmm. I'm just gonna share something, I also tried those 'Deposit Bonus' of some site, and well, I found that, yes you can play longer because of the bonus, but to actually be able to withdraw it? They put a lottttttttt of rollover requirements that it's just so sad.

So, anyway I just now look at the HE offered and choose based on that, as well as the events held by the site, I find that it offers more chances for me to actually win some. Still, goodluck to you. (maybe you could get over the rollover)

Because they know you will lose everything you have in your balance and your chances of winning the bonus is next to nothing and their lowest rollover bonus as far as i know is from their cashback bonus and daily reward (deposit bonus) which is set to 100x.
