P.S. Once you are married, your money is her money. Share everything. There's no, "money I give her"; there is "our money". If it worries her too much that she can't stand how much bitcoin you own because of its volatility or the fact that "it could go to zero", then you need to sell some and/or have some long, patient conversations educating her what Bitcoin is.

My wife and I got married in the deep of the bear market, May 2022. She had a job at the time, and we were saving all her money in a separate account and living off my money, because we eventually wanted to live off my income. I had everything in bitcoin. She started getting worried and talked to her parents about it, who in turn talked to me. My parents also repeatedly talked to me about it. I kept my conviction and held through it. Eventually we had a kid, and she quit her job to say at home. It's only been in the past year or year and a half that she's said she trusts me saving the money bitcoin. So, it may take time for her to come around to unity with you on Bitcoin once she sees the price appreciate to a certain point.
