There is already exist some Ethereum-based token, with ticker SXAU, and this have just 256 holders.
Like a sXAG, this is a metal associated tokens of Synthetix System gateway.

Maybe, for SatoriGold, can be selected the ticker SAU (like Satori Aurum)? Or something like - MSG (Mineable SatoriGold)?

There is used three chars, for this two variants of tickers,
and no one asset, or coin, or token, I do not see on CoinmarketCap, with this tickers.

But be careful! This is a very important action and this is a historical moment,
because we all, can select this for long, for a very-very long-term, up to 50 years, or even much more!
So, this ticker should be easy to pronounce, simple, recognizable and memorable.

What about KGG (KiloGrams Gold), or GKG (Gold KiloGrams), KGSG (Kilograms of SatoriGold) - all this tickers are free.
Maybe someone has better and prettier tickers?
