I believe Cashu's USP is "privacy" as they ride on the notion lighting is centralised in terms of data collection, not private, user data exposure, security risk etc - this was articled passed on : https://abytesjourney.com/lightning-privacy/

I don't know if anyone has dived into this, quantify providers vs services and determine accuracy of this claim. But if there is I would love to know more

If Cashu is to target niche markets on specific privacy requirements, take on the Tor approach then I get the gist. However at this point, they plan to have a wide target market, which means cashu taking over a large amount of sats' circulation. I think this is a very bad idea. Having said that, so many others can also start establishing tokens of their own and do whatever they want in the name of "Bitcoin privacy".
