It’s really non-obvious to me that there is any advantage of crypto that makes its use inevitable in financial products. Those Australian banks - are they crypto-related products in the sense that they appeal to crypto people (maybe a way to buy or trade crypto?), or are they actually more efficient versions of mainstream products? The idea that banks will inevitably adopt crypto because their crypto-using competitors will be more cost-efficient seems implausible to me. I just don’t see the mechanism for crypto being a cheaper way of doing things.
