In the title I had wanted to use the words "could be a lifesaver" instead of "is a lifesaver", as I am not certain of this, and certainly haven't studied it. But the title would have then exceeded the maximum length allowed on SN.
Some things I found in trying to understand more about how bitcoin relates to the velocity of money.
BTC010: Bitcoin & Layered Money W/ Nik Bhatia (Thoughts on the Velocity of Money segment begins at 0:32:25)
Bitcoin mitigates the inherent limitations of traditionally sound stores of value while also harboring the potential to meet today’s monetary velocity needs as a medium of exchange. For this reason it has entered the contemporary financial whirlwind as a great decomplexifier. It introduces a natively digital token with immediate cash finality, while simultaneously assuring holders of a fixed supply by way of a decentralized ledger. BTC is also the first ever digital bearer asset, and it can be self custodied with no counterparty risk.
The technology of bitcoin allows you to build a system, peer-to-peer, that doesn't require debt for velocity of money. And what I just said is probably the most important thing about bitcoin.
Even fiat has kind of slow settlement times.

In the last Tweet of this Twttter thread is:
Broad Summary: Settlement intermediates create time delay and require debt to function.
Because bitcoin can settle “physically” at the speed of light, money velocity is no longer constrained by debt.

Here's a paper that looks at velocity of money for "crypto", but I didn't do much more than skim it.

Another paper that I didn't do much more than skimming for nuggets:

This following Reddit post (and concepts) is describing a somewhat related concept. It was interesting. Just thought I'ld share.
nobody seems to be discussing this (money theory and lightning network) https://reddit.com/r/BitcoinMarkets/comments/8qtwvd [Teddit]
