Here are my 2 sats
Two people with differing values (and that will be nearly everyone to some degree or other) can choose I think one of these three options:
1. to either agree on every value
2. to agree that values will be different in at least some dimension(s) and be happy with that
3. to allow for unresolved tension to build until some future explosion happens
If you guys choose the second option for the bitcoin dimension(s), then i think you’d want to outline what that looks like for you guys so that it’s clear what behavior each of you are ok with. First thing that comes to mind is a budget line item, which is probably part of saving for the future, that goes to bitcoin purchases. Buying more bitcoin than the budget would violate her expectations, and cause her stress. Same in reverse (that would be the option 3)
She will need to be flexible that your budget won’t quite fit in the normal mold, and you’ll need to be flexible that you’re going to spend more fiat, and save less bitcoin than you might like. Some things are more important than peak accumulation, and a happy wife should be one of them.
