Can someone tell me some basic infos about this bookie?
Do they limit players?
Do they allow multiaccing (this is an anonym bookie, so they should)?
It's a crypto+ fiat bookie and casino with sponsorships/partnerships with 2 EPL teams, 2 Brasileiro Serie A teams, to start with. That means a legitimate business that requires them to comply with KYC/AML laws. So, not an anonymous bookie, and operating like any other legitimate enterprise in compliance with financial regulations.
Many happy regulars such as myself, if you gamble casually, you have nothing to worry about, is all I can say. Limits, as ralle14 points out, applies to any successful book. A book promising you otherwise doesn't have good risk management, I'd not feel safe there.
I placed my predictions on time, but pleaseTell me what is your best score in 6-6 promotion?
It's just to hard for me and most I had two correct predictions so far

1/6, Absolutely my best performance, for a grand total of 6 times out of all the editions I've ever played in (which, I believe, is all but one during the start of EPL). Our season EPL pool should give you an idea of how hard it is to score exact scores -- I think I got 6 in the very first Matchday four seasons ago...
@kryptqnick Love the pics!
