But I think the main thing is still bitcoin's ability to store wealth, and a lot of people will prefer to have their wealth in decentralized assets whether precious metals or bitcoin, rather than to have them in USD, AUD, etc. that is centrally controlled.
Not sure how I feel about this. I'd really like for Bitcoin to be the world's most used currency, a truly global form of payment accepted readily by anyone, if not accepted above all else. At the same time, if that were to happen, then we'd need most of it in active use in circulation - unless it became worth so much to the point that mere satoshis were enough to pay for most things. Either case is unlikely to happen, at least not in my lifetime.
I don't think that the ability to serve as a every-day global currency is hindered by the fact that individuals or organisations such as central banks may use it as a reserve currency, or store of wealth for the long term in an individual's case. They are not mutually exclusive.
