Yeah, I personally don't mind Lightspark since it helps people onboard to Bitcoin. But the privacy concerns are there, hopefully we can get Cashu improved enough to make it the default custodial solution in the future for WOS.

Spark isn't too bad compared to other options. Only time will tell on how it grows.

They will keep both. Since it's easier to onboard people without them needing to learn seed phrases immediately. But over time I think people will learn to secure their wallet with seed phrases.
