You got me at don't hide your crypto investments from her 
I mean you can show her something but should it be all of it?

Yes! The more you are able to share with your partner the stronger your relationship will be. There's also a difference between hiding it vs it just never coming up because she doesn't care and it doesn't affect your overall finances.
