Thanks. Yeah, you really cannot spend your bitcoins...
About Phoenix, what pull me down when I tried was the initial setup. So you open the app and the first thing you see is "we'll take xxxx sats on fees". So maybe they should communicate this better:
"You'll pay some fees in advance, but then you'll use your own channels and save on fees wrt other wallets", or something like that.
Anyways I want to try it again.
