One major problem I can see with something like bitcoin is it tries to pretend to be Gold (only it’s not gold)
Now let say you could take out a 30 year mortgage that you pay in Gold and only physical Gold (that something like bitcoin pretends to be).
OK so say your mortgage is 1.5 ounces a month (in physical Gold), “what’s that $2500.00 or so”
Now 29 years later your payment is still 1.5 ounces a month (in physical Gold).

Can you see the problem with that, just saying.
That is why deflation will not be allowed to happen IMO.
