Having read a lot of Bitcoin books, each one giving a particular insight from each author 

What I particularly liked about @LynAlden Broken Money was the explanation of early forms of credit 

Ie I give you something of value, if we were in a high trust tribe, then I would be happy noting down that you owe me something in the future, & storing that debt in my head. Ofc this doesn’t scale. But it pre-dates money in a sense. 

Point being, I absolutely agree there will be a credit market on a bitcoin standard, it will however be radically different today, in large part due to the cost of capital being much higher, therefore debt risk much higher, so interest rates will have to reflect that 

Fascinating one to watch play out 

 Which in turn means the debt won't be used to fuel non profitable nonsense, as that'd lead to default. Instead debt would be used to fuel the best, most profitable ideas only. The 10x, 100x or 1000x ideas.
