Are those hard concepts to grasp?

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.
