The twitter account of the project is not the one you provide, it is: https://twitter.com/bitcoincz_org
If you were scammed by that person, go to him, the project is legitimate and is working.
Indeed, the collateral for a mn of bcz is 5k bcz, if it seems excessive, you can also bet your coins in Cold staking, it has no cost for users and they can earn bcz as a reward.
But the Twitter profile is affiliated with your project, right? Just like this Bitcointalk profile (DrPlanck)
Your thread is also heavily self-moderated, I hope you didn't delete legitimate questions about your project because that can be uncovered.
