I really thank you for your understanding. Two days I often find a way to learn about Bitcoin, how my brother lost that precious amount. And now I know it was really lost, but never regained it.
We did not give up, but we could not do anything. We tried our best, worked without rest and thanks to the help of social banks to have money to treat my sister at the time of gold surgery.
Now I may have to accept it. Accept the loss of a person who does not love, is my younger brother. I will never forgive him for the rest of his life.

But I could not bear to see my sister's pain. That problem should have been resolved next week. In surgery and treatment there is always a chance of success, albeit small but still at 10-20 or 30%. However, for my sister now is 0%, a perfect number, because she has no chance to get it.
