Is always interesting to look charts in the long term. In the case of bitcoin we can see how it has always been following that chanell unless it is in a bull run but then btc return to the chanell if btc continues with that patern we could see a bottom in december(4000) or in february(the actuall price) i think that is more provable in december. Once we reach that point we 'll have to options :
1- continue going up and up in the chanell till reach 20.000 and the provably start a bull run as it happened in jan 2017 wen we reached the previous high of december 2013.
2-BTC breaks the chanel and goes to 3000 and then to 1000.
i think that the 1 option in way more probable but lets see what happens we should know it in the following months.
