An observation:

In the first cycle (Bitstamp), Bitcoin dropped 81.26% (Keep in mind Bitcoin traded approx ~50% of this cycle)
Second cycle, Bitcoin dropped 86.89%
Third cycle, Bitcoin dropped 84.12%
Fourth and current cycle so far Bitcoin has dropped 77.34%

 2nd, 3rd, and 4th cycles have seen the majority of adoption which has increased each time.

IMO, if you're waiting to buy at cheaper prices, you're gambling.

This train waits for no one. Don't get r0ached
