They will use new layers, federationd and sidechains of Bitcoin
Discussion
Doubtlessly, but there's a big difference between getting sats into cold storage on layer one and running a lightning node. For a pleb like me the first is attainable, whereas the second still is more than daunting.
So yes, self-custody is preferable, but at some point there might be a need to start rethinking the role of custodians and trusting them
I am in the same boat as you. Tried many times to set up a lightning node and always ended up giving up. nostr:npub1utx00neqgqln72j22kej3ux7803c2k986henvvha4thuwfkper4s7r50e8 has been talking anout #liquid recently. Thar seems easier to use and is less custodial than a custodial lightning wallet
It would be great if there will be non-custodial solutions on higher levels of bitcoins. Especially because I don't see how on earth it will be lossible for everyone to even get any number of satoshis on layer one.
For many in Africa, Asia and South-America the first layer won't be an option, but holding bitcoin with a trustworthy custodian will still be a solution for many to get out of the inflation prison that their local currency puts them in...
