I often think about this nowadays. We were on a spectacular uptrend. Core team was about to launch 0.13 and the halving happened, we were on the good track, but Bitfinex happened, ruining the good uptrend with the stupid as dump. Fortunately we recovered quick, but the uptrend is not as strong and will take some more time now to go 1000+ again.
Actually i don't think so thats all because of Bitfinex happened and than bitcoin down, but i accept it litter bit Bitfinex affect on bitcoin price, but i believe that was a time to start the bitcoin down, because halving already give us a profit, and many peoples sell their bitcoins so bitcoin was mustly down if Bitfinex happen or not.
The price dump happens on the day when bitfinex got hack many people got panic and sell their all btc because they know that price would falldown since the hackers stole a lot of btc and anytime if they dump the price will gonna go down and that is currently happening now, and if bitfinex didn't get hack i think provably the price of bitcoin will go to 800$-1000k$ and we provably go down stable at 700$ but things are just happen and it is a relief that bitcoin is currently stable at 550$+ -600$ in price nowadays.
