I could see the next ATH being preceeded by something like a "Silk Road Flash Crash" to $400 where China completely outlaws Bitcoin and all the Chinese exchanges shut down but then BTC bounces all the way back to $700 anyway within days or weeks. I'm not saying it's going to happen but it would be amusing.
After the Finex fuck up, China became more of a leader than before, and can take us any in direction they want. If you thought previous price manipulations from the dragon was something you haven't seen anything yet.
No idea where all USD traders went since clearly they're not on Finex anymore
