Nice! This also shows that lightning is ready for the deflation activities of the increased buying power of Bitcoin. 

Fungibility through math and not liquidity through increased supply.

John Carvalho proposes BIP renaming sats as bitcoin

lightning can go lower than msats, it's just a unit attached to an invoice, see [BOLT11](https://github.com/lightning/bolts/blob/master/11-payment-encoding.md#human-readable-part):

> # Human-Readable Part
>
> The human-readable part of a Lightning invoice consists of two sections:
>
> 1. prefix: `ln` + BIP-0173 currency prefix (e.g. `lnbc` for Bitcoin mainnet, `lntb` for Bitcoin testnet, `lntbs` for Bitcoin signet, and `lnbcrt` for Bitcoin regtest)
> 2. `amount`: optional number in that currency, followed by an optional `multiplier` letter. The unit encoded here is the 'social' convention of a payment unit -- in the case of Bitcoin the unit is 'bitcoin' NOT satoshis.
>
> The following `multiplier` letters are defined:
>
> - `m` (milli): multiply by 0.001
> - `u` (micro): multiply by 0.000001
> - `n` (nano): multiply by 0.000000001
> - `p` (pico): multiply by 0.000000000001

This means that a lightning invoice for 100k sats starts with `lnbc1m` because 1 mBTC is 100k sats.
