Technically speaking, by established norms for determining such, HEX is not a scam. It is, however, a giant shit token, and this picture is all you need to know about what it does.
I'd say it depends a bit on how you define "scam". At the very least, it's shady as hell. They have (or had? I've read about this when HEX was still relatively new, and I don't know if things have changed, since then) this copy function in the smart contract, which gives:
- "someone" (wink wink) an identical copy of the HEX tokens someone "minted" (I don't know how to call it)
- and of course the ETH paid for the HEX tokens also goes to that "someone"
It is an ingenious money printing machine for the creators, i.e. Richard J. Schueler ("Richard Heart"). People need to decide for themselves if they want to help spread something like this. I, personally, wouldn't.
