I think Richard Heart owns this project, he lost his reputation because of this, in his debate with Tone Vays he is so good at defending his project, so many favors him, but unfortunately many people see his project as a scam project, because people are more matured now, even if you are an experts and with names in the industry, people will not just believe them.
I think the problem with HEX is that it only pays out people rewards from inflation and withdrawal fees and the distribution of it isn't fair at all. Since HEX's release other platforms have improved upon what they have done and adjusted the contract and added features. MAXX finance is the newest one to launch and it is distributing revenue genereated from token transaction fees, validator node rewards, and a future suite of DeFi DApps. It has fixed yields based on real revenue. So you see, the concept of a tokenized CD is valid, and the developer on it did a good job on HEX, but it was the founder, distribution, and MLM techniques that made HEX look like a scam.
