He should have let her leave him. What a bitch. You don't threaten the person you claim to love like that. I would have told her to fuck right off and left myself. Legally they can do jack shit to you.
It is your crypto so no law in the world will take them from you. I know a lot about the law since my brother is a lawyer.
You should not have to be in this situation, to begin with. If you then find a new wife. Don't marry idiots or stay with them. It actually is disgusting that a woman would threaten her husband like that.
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.
There is no law that says you have to give your crypto and you don't need to hide it. You cannot get someones bitcoin. Put a gun to their head and make them enter their privatekey? Nothing will bite you hard. In this situation you could tell your wife to fuck off and that is that. She can do nothing. Not her bitcoin. If they happen to be heres and his then this is another story.
Even if there was such as tupid law I would just laugh at it. Law is man-made bs anyway. Most laws are made by a bunch of twits in a room with their own motives.
