I don't get the same feeling. Bitcoin, it its lifetime will grow higher than current levels. But thinking about the activity in 2017, the reason I'm not concerned is because we've had about 11 run ups this year. We've had 11 new "record high" marks set for valuation. And immediately following each new high mark we see a pull back, a correction of 10-20%. That's the size of a correction in the stock market, it's normal.

What's not normal is how quickly it happens with Bitcoin. And then how quickly new money comes back into Bitcoin and adds support to stop the correction and eventually build momentum to set a new high mark. I've watched it happen 11 times thus far. Their may be one more cycle in February. These cycles happening every month is not typical in the stock market, but Bitcoin is not the stock market.

The corrections relieve the price pressure, people take some profits and then we reset at a new level.

I'm not saying a crash (greater than 20% decline) could never happen or won't happen, I'm just not worried about the price growth of 2017.
