I think what the banks mean when they say this sort of thing is "we're failing to find a way of appearing as if we've not been outmoded". Their model is dead in the water, and there just isn't a way to do "blockchain banking", it's an oxymoron. They're anathema to one another (banking and blockchains), that was how and why Satoshi wrote the Bitcoin source code to begin with.
Couldn't have said it better. Banks are fooling themselves into thinking that they can remain in control by starting their own altcoins. They will fail and burn a lot of money in the process. If they would be wise they would by some BTC with their remaining capital, but their arrogance and feeling of self-importance is hindering them.
The age of banking as we knew it is over. From now on, people will be served by Bitcoin.
In future, today's banks might become insurance companies for financial cyber threats. But only a few specialized banks will be able to establish themselves in that field. The years of plenty have passed for banks.
ya.ya.yo!
