This is not a good strategy to incentive users reach the high level rank just to be able to join tournament poker event. When the minimum wager required was 10K, anybody got motivated to deposit more for to lucks one is to win one of the bets, the second is to increase the minimum wager to reach VIP level and benefit from exclusive features like the poker tournament event. Now users will find it quite hard to reach 50K wager and probably they will forget about the whole thing and may even leave the casino.
For sure people will start to forget it if their main reason playing in Yeet is merely for the poker tournament especially if they started to be interested before the minimum wager is increased.
Even with $50k wager requirement, $5k poker freeroll every 2 weeks is still a great offer especially for those who like to play poker game.
Basically it is not that hard to wager $50k even for small bankroll players, as long as they wish they can do it by betting small amount only to minimize bigger loss but it should be done frequently.
