I never said blockchain was a solution. I literally just said there are features of cryptocurrencies that are useful.

There are features of cryptocurrencies that would actually be useful in today's financial services.

The main one would be near instant settlement.

PayPal makes billions offering this service, when it could be a feature of the financial system.

You seem to be doing this weird thing where you're trying to imply cryptocurrency is solving a problem, but still wanting to have take backs when people say "cryptocurrency doesn't solve this problem".

If your position is that instant transfer would be useful, there is no reason we don't have that already at a technical level. It's purely a financial system construct that we wait and have settlement periods for the ability to reverse transactions, have added security, etc.

If your position is that cryptocurrency somehow solves a technical problem, I'd be interested to hear what you think that technical problem is.
