Yea slowed down my gameplay on stake as well because found it harder to win but let's say my negative balance a little lower than yours. Also, it does help to get bigger wins if you deposit more but that's up to you and how much you can afford to lose.
Hey, in my opinion it would be really cool if you can send out bonuses to the players that loose consistently and are overall down a significant amount on the account. They don't have to be big. It can just help the player out no matter if its big or small and make it seem like you care about your higher ranked player's that started with depositing and wagering large amounts to them having to slow down their game play because of consistent loses and not receiving as much support from you guys anymore.
You guys ever feel that after your first big win on stake, mine was plinko. Did you ever find it super hard to try and get a big multi or cashout? Also, I feel like the higher rank you become the bonus's get smaller and you don't receive them as much anymore.
