There is a distinction there. Every transaction of every bitcoin is tracked in the public blockchain. In a way, there is no system that is more traceable than modern crypto currency. However, the identity of the owner of the bitcoin is not necessarily known. There are analysis that may allow a person to associate an identity back to a transaction. Falling prey to those methods are because of failures of operational security by the coin holder. So if you can get your grubby actual or digital mitts on somebodies bitcoin wallet by coercion, hacking, or whatever, those are your coins. It's just like stealing cash in that case. So to me, that's why it makes a lot of sense in the setting of this game. If the MC beats up/teases up some alien and nab their credits, the idea of a decentralized crypto currency makes sense, just like gold coins makes sense in a fantasy setting. How can I possibly do that if it is reasonably protected by any sort of security? If everyone is using some government backed credits in TiTS, which law and order has their hands in, what you'd see was an alarming pattern of assaults, rapes, and thefts performed by one X Steele. I'm sure some of the transactions from the accounts of the various aliens to Steele's would be reversed over the course of the unending number of court proceedings. That gives me an idea. TiTS: A Court Drama. Eck.
Anyway, if you want to keep nerding out about cryptocurrency, please message me. I was just saying that I don't think normal banks would make sense in this future for multiple reasons, and how I imagined the credits worked bolstered that in my imagination.
