My people still afraid of bitcoin because the value still volatile and their government also not support bitcoin
But IMO if you have enough money and dare to take the risk of investation , it's worth to invest on bitcoin ! ( hold at least 1 year, PROFIT ! )
It seems to me that the bitcoin community does not need those who are not confident in it. Bitcoin isn't a currency as it seems at first glance. He is constantly in a state of volatility. This means that the person who doesn't believe in bitcoin sell your coins at the first dump. So I think that your friend is still too early to buy bitcoins. They have to be ready.
