The corrections were inevitable, unfortunately people tend to freak out because of the "scale" of them and panic sell a bit, making things somewhat more dramatic.
The shitty uptime of Coinbase/GDAX during yesterdays "to the moon" period probably didn't help new-users confidence too much, but that will settle out long term.
A fun thing to do is compare the % difference in BTC/USD corrections to normal, daily corrections on the USD/GBP Forex market. I'll leave this to you to try, no spoilers ;)
