I don't understand what makes a cashu ecash token more bitcoin than a liquid Bitcoin. They both aren't.
Discussion
I have experience with RSK (similar to Liquid) and i had problem to withdraw satoshi... Easy to get in, hard to get out and more centralized solution then cashu (midleman to withdraw). And Aqua wallet who offer diffrent shitcoin (Tether). To many red flags for me.
I can compare liquid is like Tether.
Liquid - Bitcoin
Tether - USD
One day people will wake up and realize that they have lost their satoshi. In the case of cashu, it will be a much smaller amount than liquid.
Cashu is more decentralized, like protocol.
