How to find a good wife, Bitcoin edition:

How does she react when you bring up bitcoin?

Is she curious? Encouraging? Positive?

Indifferent?

Mocking? Critical? Negative?

The first 3 are more likely to be indicating a good woman.

Next, check her response to other things you like.

If you bring up something you regret or something she doesn't like, how does she react?

If she seeks to understand, or comfort, or check if you've grown from the thing you brought up, that's a good sign!
