Given how breathtakingly simple the space actually is, inventing big words and forcing other people to learn them really only serves to stroke an ego.

"watchtowers" is a big word now? as for "inbound liquidity", I guess you can argue it's big because it's a compound word, but it's relatively easy to understand ("liquidity" is a standard term in finance, for instance) and I can't think of how you can shorten it further without reducing comprehension.

Compared to cash in my wallet, a credit card, or cryptocoins held on chain? Yes.
