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 ass dump. Fortunately we recovered quick, but the uptrend is not as strong and will take some more time now to go 1000+ again.
i think somewhere between $600 and $650 and nothing more. because the bitfinex hack only caused a temporary dump which only took like 2+ days to recover and since a resistance shaped up at $600 we couldn't break it yet.
also before the hack (the day before it) the price was going down a bit reaching $600.
this is why i think the rise is on the way but we are not ready for it YET.
