https://bitcointalk.org/index.php?topic=5309733.0You were had a problem with stake with your €4,000, and you confirmed you have got your money back from stake. So, the best sportbook for you is Stake.com, or are you afraid to play on stake again and looking for other sportbooks?
He has a lot of choices. If he wants to try another sportsbook, he can do that as he please himself. But he got the experience through stake and it's up to him whether he's satisfied or not.
You have plenty of choices to choose from OP, you can take your time researching and trying each of them if you got a lot of time.
