BTC is a better investment then AAPL??? I LOL'ed. 
All depends on what price you got in at. Bitcoin has massively outperformed Apple this year.
Anyone who bought bitcoins in the last two years until a month ago has seen MASSIVE returns on their HIGH RISK investment. Apple represents lower risk. Nothing about their respective price gains nor losses should be surprising. One is more volatile than the other. That's about all we can say about their appreciation.
It's a high risk investment with an extremely low risk/reward ratio. You have approximately a 30% chance of making 10X your original investment. Any poker player would jump at the chance.
Apple is out there. All growth is already priced in. Bitcoin is an obscure product still in beta. Seeing the value in bitcoin requires awareness of its existence and above average knowledge of encryption and economics. And bitcoin isn't dependent on a founder/CEO that's dying.
