> 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.
