I have been thinking about something similar and related to this a lot recently.
I've been wondering if adopting the term "bits" in place of BTSX or the previous suggestion "bips", which does not seem to have gained any traction.
I think it would go a long way to helping users understand bitassets relation to BTSX, and would make the naming of bitUSD, bitGLD, bitCNY, etc. seem more obvious.
