I don't know if you own your own house, but I feel this was a smart choice based on the fact that your dad is concerned on your mum not having a stable place and having to worry about rent when he's no longer there. I don't know if he knows about your internet enpire but for sure be might still be in awe in bow you and sister managed to pull that one off. It's great to put plans like this in place, like you said, when one has wealth in Crypto it's advisable to own things. Property and all. Congratulations.
