Thanks everyone for your concern on our situation. Showed the thread to my dad and he's appreciated it a lot. He loves the fact total strangers cares so much about him as he's not used to it in the real life.

BTW yes, I made him aware of all the risks. He's just got that tiny amount for now, but he doesn't exclude he may buy more in the coming months. His goal is not to get rich off BTC, he just likes this "new" kind of money where banks have no control, to him it's a revolution.
