Sooo... completely centralized?

That's a hard no.

I briefly scanned through the whitepaper at:

but couldn't find how it solved the Byzantine General's problem, transacting without a need for trust.

Nobody uses Bitcoin that way--everybody uses the very centralized and very identified brokerages like Binance to actually buy and sell it. The libertarian fantasies of "currency without governments" never materialized nor will it.

Bitcoin will always be just another speculation instrument because it's too slow and too expensive to used for any other purpose. The reason is this useless religious garbage called "blockchain".
