STIX, seems, like free. It is easy to pronounce, but the meaning is ambiguous.
Maybe STIX means a "SaTori Internet/Innovation/Information XAU"?

What about just SAG (SAtori Gold)? This ticker is free, and have 3 chars, like BTC.
Also, SAG, this is a alive abbreviature: https://www.abbreviations.com/SAG
so many group of peoples can know about SAG, and wants this SAG, hehheh.
