Yes, e-cash built on Bitcoin will take place of it
I'll give you a chance to prove yourself. open up tor browser. if you're really lazy, open up a tor tab in brave browser. go sign up for dread and try to shill cashu to the DNM people who congregate there. see what happens. maybe someone on there is brain damaged enough to fall for it, but you will most likely just get laughed out of the room. ecash is custodial garbage.
Nah. Maybe doggie coin stealth payments or something
ecash is custodial so no that said if BTC implements strong privacy i will happily use it
Ecash is already a non-starter as a replacement for Monero. It's custodial. Even Calle the creator of Cashu has said this.
