In all, every casino is unique in their different ways, we the gamblers are the ones to search and choose one that really meets our expectations and stick with them, there is no perfect system anywhere in the world.
Problem here is that we cannot stick to such sites even though we like them a lot due to limits/restrictions on certain popular sports which is why we end up shifting to other platforms.
Sucks that so many sportsbooks chase away winning gamblers quickly, but it makes sense from a financial point of view.
