That's what the Minibits is for, right? Or is there another ANOTHER component?

I was thinking that Minibits is a debit card,

and the mint is a checking account,

and the LN node is the savings account,

and the Bitcoin wallet is the gold vault.

And it would be n:1 for each level. So, n Minibits wallets for each mint, n mints for each LN node. I guess LN-BTC is n:n.
