So in the telegram a few of us were discussing and agreed that the Σ is hard/confusing for people. The word Sigma is great because we have Sigma Protocols in Ergo (which no other blockchain has) and we have https://sigmaverse.io, meaning we have the branding already all around this.
As such we can keep things simple (and not try to take over a ticker, which is extremely hard to get CMC to updated anything + I’ve never heard it done before for Coin Market Cap, so I don’t think this is a realistic plan), and maybe just go with:
SigUSD (SigmaUSD)
SigRSV (SigmaRSV)
