What if I asked you back, if you were in this situation what would you do.?
Your love for your little sister cannot be measured by anything, you will do anything to save her including selling the most valuable asset you have ever owned. When other funds are not available, there is no need to think twice about taking a stand. let alone Bitcoin, the house that leaves the most memories you will sell in order to save one of your family members.
