his wife had heard about Bitcoin in the mainstream media and the price rise and was pressuring him to cash it all out immediately or she would leave him.
If it had been mine before she arrived I'd tell her to go fuck herself. If it were 'our' money that would different. Even then someone like that would've told you the same when it hit one dollar. And after that they'd spend what little time left you had together berating you for giving in.
It would also be a completely different deal if we were under significant financial strain. Not addressing that if you have the means is selfish and stupid. If things are bobbing along just fine then it stays put.
And when you get your divorce Bitcoin is worth something so you're going to have to give whatever the court decides away. You can try to hide it. That might bite you extremely hard in the botty.
