I didn't sell anything (still HODLING my bag) so I neither made nor lost anything.
Much of the same. I wanted to do something with my bitcoins when it hit the $400 margin, but was too hesitant to try anything with it.
Who was going to know when the bubble would pop?
Pretty much this. One of these times, it won't pop, until it gets well over the previous ATH. Maybe you got lucky this past mini-bubble, maybe next time you won't.
