You're right, maybe the OP will regret it more when he prefers to keep his bitcoins. What you do is right even if you lose bitcoins but you still have something more valuable than that. After all, saving someone would be more important than anything else. If I were in the OP's position I would do the same thing as the OP did.
Just imagine if you don't do it for your wife, maybe you will regret it from now on and maybe you can't forgive yourself.
Maybe I will say, do not regret because something you do is more valuable than anything.
Besides all that has been said, I would like to add that it is never too late to start over. At the moment, starting probably in the spring of this year, I started all over again and started buying bitcoin, but now everything looks more complicated, the price is higher, but there have always been and will always be difficulties. You can start over and achieve even greater results, the most important thing is to understand that there are people nearby for whom you want to do this.
