I can't find any information on nvidia or about nvidia backing the nvidia token.
Here as stated on the website nvidia.io
"Why Us ?
NVIDIA Coin is a permissioned blockchain digital currency proposed by the company NVIDIA. The project, currency and transactions are to be managed and cryptographically en-trusted to the NVIDIA Coin Association, a membership organization founded by NVIDIA and 27 others across payment, technology, telecommunication, online marketplace, venture capital and nonprofits."
Sounds like utter crap. But I just want to make 100% sure.
