Oh, I really don't think that will happen. The fundamentals haven't change - but bottoms are notoriously difficult to call...
EDIT: To quote Keynes again: "Markets can remain irrational a lot longer than you and I can remain solvent."
Of course, the fundamentals are still there, the cryptography is holding strong, the adoption is still going up, new and useful services go live every day.

may happen. It's merely some hedging after we've entered a rather erratic (in my eyes) pattern now.
