I think we can take the opposite lesson from bitcoin.
Bitcoin was never supposed to be just bitcoin, it was always intended to be a platform for many things, but the technology has become synonymous with a particular application: cryptocurrency, and bitcoin in particular. It has applications in this area, but I think most people focus on just that area, and so there’s a risk that many other applications don’t get imagined, or don’t get a hearing when they are.
SAFEnetwork has even more potential as a platform than the blockchain IMO, so it would be even more limiting in people’s consciousness to make it synonymous with a cryptocurrency.
Safecoin also already suffers from confusion as - just another - altcoin for anyone who has reached the point of understanding that term.
SAFE (or SAFEnetwork) as a brand clearly states that this is about a set of principles embodied in a new technology, without being easily confused with, another altcoin or just a cryptocurrency.
Safecoin both leverages itself using SAFE as its root, and brings the importance of that root to the fore. Having both could work very well for both. It isn’t either or, and it isn’t negative to have two brands that link together as well as this. Brother and sister!
Nobody has addressed the point I made about apps that have nothing to do with a coin struggling to get across their unique selling point (SAFE) when the brand that they apply includes the attention grabbing, but misleading element: “coin”?
