From January to December every year since inception Bitcoin has risen AT LEAST 2.50x it's value. If the pattern doesn't waiver, you should profit.
It could be a difficult act to follow this time around. The fact that it shot up so much means that trying to maintain at least 2.5x growth is nuts. Hell, we may be looking at shrinkage this year, who knows.
Interesting point you make though.
You're right that we're not on track but I remember when I thought the same thing when it lingered at 100 USD for months until it shot to 300 and then eventually 1,150 within a month.
We'll see -- hopefully it does follow the trend we've seen thus far.
