OK, I believe it should be understandable why BlackJack.fun decided to take that path, plus the rewards from Diggy's hole. Because the real purpose of the bonus is as a "bonus". A user is rewarded for playing, because he will play without the bonus, NOT a user who plays because there's a bonus and would stop playing if there was none. It's a good trade-off in my opinion.
BUT, because BlackJack.fun has currently started to require the 20x wager, should they start to return the hourly, daily, weekly competitions back to what the rewards were before the changes months ago? I believe, yes.
I doubt that they will return the original reward on the tournament because they decided to change most of the rewards in free spin to cut cost and also they now implement to this bonus reward which means there goal is to minimize there expenses on there bonuses.
Bitcoin is decreasing and they might increase the reward in Bitcoin amount but they will still put the wager requirements to make high roller players play more to claim there bonuses that they gain on tournament. The casino has less activity since this wager requirements is implemented. They should release already the VIP reward to compensate on this new implementedwager requirementsto properly reward players that really risking there money in the casino.
