I doubt they truely raised that much. They probably inflated the numbers to create FOMO with investors.
There's really no clue as to how much they raised but they can claim anything. I dont really believe they raised anywhere near these figures.
They never try to publish the smartcontract or the wallet that has already used to raise the funds from the investors. I remember the bcnex case and it looks like the same thing happened with bankera as the project didn't raise as much as what already published before. it can be manipulated easily.
