If you've been really trading for more than a year, you should definitely know that this drop is only going to be temporary
I've watched a few $100 drops before, but a few things are different this time:
A) I never held enough for it to affect me too much
B) My alt bags used to pump when BTC dropped
C) This is REALLY starting to feel like a bubble
It's the last one that killed me as I'm not sure how the bursting of said bubble would affect my bags long term.
With that said, I think it's a mistake to assume BTC will do nothing but rise in the future.
