Thank you for beeing a good Hive citizen! :-)
No rebranding is planned, and I'm not that convinced that it would be a right path to go. MiCA is here and there are way more challenges and problems to solve more important than naming convention. Naming it xUSD makes just different set of risky assumptions.
IMHO what we need are use cases.
I agree. We need use cases. I'm of the opinion that one of Hive's most compelling use cases at the moment is being an alternative to Lightning. I'm in Central America, where bitcoin is slowly but surely gaining lots of adoption. It's already legal tender in El Salvador, where companies like IBEX and OSMO have developed bitcoin POSs for merchants, so People know the name "bitcoin". If we could make it as easy as possible for folks to pay Lightning invoices with tools like v4vapp and Keychain, then it might help drive adoption of HIVE as a tool that works well with bitcoin.
That's one use case.
