Hey Holland51167,
Did you mean to post this in our Dutch community?
Either way, I've checked your details and it looks like the Everest Poker bonus you mentioned is an old bonus you received back in 2012. If you don't have this bonus anymore or have forgotten about your Everest Poker account, I'd unfortunately assume that your free money there has expired 
It's unfortunately not possible to get this bonus elsewhere, including PokerStars. If you're interested in getting some more free poker money though, you can check out this page:

Apologies for any inconvenience caused, and just let us know if you have any other questions 
Regards,
Tino

Hey,
I have a questions regarding a bonus I would get upon registration. It says that a bonus of €30 has been credited to my account. It also states that it has found my Everest account. But I don't have an Everest account. I only have a PokerStars account and that's the only one I've given, nothing more. Where did the bonus go? Can it be credited to my PokerStars account or is it only for Everest Poker? Thanks in advance.
Regards Holland51667
