what makes that symbol the sat symbol?

2. ETH uses Ξ . the similarity to the ultimate shitcoin is too much for me 3. and this 'sats symbol' isn't a made up convention? it's all made up, we're making it all up. we've got a chance to make something up that a wider audience will be able to recognize. you really don't think that lowercasing a subunit doesn't have an immediate rationale to it, even for the uninitiated? besides, the convention isn't *entirely* novel: in computing, bytes are B, bits are b. chemistry: m vs M (molal vs molar concentration) math: p vs P (probability value vs measure)
