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.
Glad to hear that you have told your father about the risk he took in investing in bitcoin and I really appreciate you showing something new for your father which maybe this will indeed be a source of pride for him who is already at an advanced age. And I like parents who are open minded with advances in technology.
good luck guys.
