If you haven't start this game then dont. Run away now. I have 990 days played. Game is pretty much straight up pay 2 win (roughly 2k$ every couple months in kvk) otherwise you can not be competitive. No matter how strong you are. If you dont max crystal tech, be prepared to get wrecked by players who spend the 2k every KvK maxing their tech. Pay to win is a norm in mobile games. But over here, there is no skill/strategy/tactics to out manoeuvre opponents. All you have to do is spend 2k.
