Hashcoin will be extremely centralized.  Not sure how the banking will play out. Is GAW big enough with enough credibility to handle the "bank" is another question.

How has decentralization with btc worked out so far? Not so great. We still have banks and exchanges running the show for the most part. I'm wondering how much scams and thievery have hurt the decentralization idea?

Governments, laws, rules, and regulations came about because we cannot exist without them and still have a civilized society. Look at the wild west of cryptocurrencies.
I digress. Sorry.
