I think the creators of this project have chosen a very right direction. Now, many are trying to implement such gambling projects based on smart contracts and blockchain.
Yes, I agree with you, only in this case, the project creators approached this issue much more closely than some others. The idea of the lottery is much more advanced.
I like the fact that this project has a long-term perspective; now a niche of blockchain-based financial pyramids, for example, 333 ETH, is very actively emerging.
By the way, this project also has a smart contract managed by all stages of the project and the development team does not have access to the project fund.
