So I've decided to pull the trigger and go with my 'gut' on this one; I'm changing the store to a Bitcoin Only store. Thus, the name 'Cryptonaut' needs to be changed as well. This is the best idea I've been able to come up with (after consulting ChatGPT for hours, as well as some friends/colleagues):
CoSatoshi (コサトシ)
Advantage: keep the "C" as the first letter, making rebranding much easier
Disadvantage: technically in katakana it would be spelled KoSatoshi (and I much prefer 'K' over 'C')
I can't find CoSatoshi taken anywhere else, so it seems like the best move unless anyone else has any better suggestions/ideas. Feedback welcomed and appreciated 🙏🏻
