Just to be clear, I'm not saying it won't drop from here, which in itself is probably a bullish indicator. 

A bullrun on fiat? yyAy!

I closed my short on the way up from 350 to 360 in a hoped to reopen it above 370 but I am starting to "panic".

Just stay patient and hope for the best seems like better advice. Some random swing will meet your bids/asks eventually. Maybe.
I prefer to substitute the word "trading" with "gambling"
As long as you enter each position with the expectation that you could lose everything, then I think you'll be fine.
I'm afraid of a situation where retail investors get involved and get slaughtered.
That is the main thesis for "as low as possible for as long as possible."
