That preceded the public face of the Mt. Gox situation, which is what the original comment refers to.
There are always small speculative bubbles here and there, it happened exactly like that 6, and 12 months prior. It's interesting how bitcoin prices are highly cyclical. I think there's going to be ONE MORE expansion, in approximately 3 months, that takes the price of btc to about 5k, although it may pop as high as 10k on its way. If for no other reason than there are often self-fulfilling prophecies in finance.
