There is something profound in common American "rule of thumb" wisdom. For example...

1. "A bird in the hand is worth two in the bush."

2. "An ounce of prevention is worth a pound of cure."

Simple and effect. The roots of these easy to grasp phrases are found in St Thomas Aquinas words - paraphrased as ‘the slenderest knowledge that may be obtained of the highest things is more desirable than the most certain knowledge obtained of lesser things’.

‘Slender’ knowledge is here put in opposition to ‘certain’

knowledge. And what is this notion of "highest thing"?

Who determines what higher things are? I am pretty sure most readers here will agree "self-custody" is a higher thing than custodial.

Are there more Bitcoin distinctions?
