NOT Logo Mask
Sponsored by the famous Not A Security (NOT) ERC-20 token.
Not many people know this, but this logo originates from the well-known Not A Security (NOT) ERC-20 pyramid scheme. According to some inside sources, the creator of this token is facing intense legal action from the SEC and needed to auction off some of the IP form the project to help pay for his legal fees. A good friend of mine was left "holding the bag" and lost a non-trivial sum of money with this scheme, so I can't say I'm a fan... even if the logo is as good as it is.
Great logo. Good for "seeing" what's really going on around you.
