Re: Before Bitcoin hits 1 000 000 usd, it falls below 10 000 usd
Yes, there have been many many micro-level (or crypto-specific) crisis, but no macro-level economic crisis like 2008 or 1929 during Bitcoin lifetime.
Then short it or you are just full of shit. Show us your open short positions. 
The market can stay irrational longer than I can remain solvent. What if BTC price goes even to 130 000 or 150 000 before the crash?
If I am right, I need not to take such risk.
