I'm 17 right now and I have around 0.5 in btc right now. I've been asking my dad to invest in bitcoin for so long. Today he finally agreed to loan me $10,000 CAD to buy around 10 Bitcoins with. I have two questions. Firstly, is this a good idea? should I invest in bitcoin (I'll leave the money for around 4-8 years) and secondly, where can I buy 10 BTC online?
