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.
