The whole BTC ecosystem has matured a lot since then. Besides, many people would just
add to their holdings in the case of a correction.

The amount of outstanding bids on the exchanges has increased dramatically.
You only have to look at Bitfinex and Bitstamp to see more
than 100M $ in open bids. Besides, the exchanges today are much more professional, which
attracts serious investors that wouldn´t use a sketchy unprofessional exchange.

Therefore I don´t think corrections like that are really possible anymore.
