Just like in the content of OP, I am a stake participant and I do receive my pay in my stake account but never have i used it to gamble. The thing is, I am more of a sports bettor and I'm comfortable betting in local sportsbook using fiat.
At the same time, gambling with your signature pay might force you to go against your bankroll management. Which is one mistake I wouldn't want to do.
I remembered, I used to gamble my funds when I still participated in the campaign signature of blackjack.fun given that they paid well during that time.
Back in those days, I would use like 50% of my signature campaign earnings to gamble at their website given that I receive their funds directly into our respective accounts in that website. It was both a fun and dangerous experience given that there were times where I used everything in one sitting.
The answer is affirmative, signature campaigns paid to casinos actually make you to gamble. There are some instances in which the payment for signature campaign is less than the minimum withdrawal, in that case one will be required to bet with it to aim for the minimum withdrawal to be able to make withdrawal. Apart from this, the temptation to gamble when you have some balance is very high which is why payment of signature campaign into the casino actually make one to gamble more.
I also remembered that there was a time that you couldn't withdraw your funds from that gambling website due to the minimum withdrawal requirement. When I was still Jr. Member many years ago, I had trouble withdrawing my funds and it took me like 2-3 weeks of pay in order to withdraw directly to my wallet.
