Interesting that we have been in that middle channel for so long. Even if we followed the lower channel we'd be in decent shape long term.
That chart is by PentarhUdi aka Masterluc aka Bitcoin Vanga - his forecasts are well respected by a fair few people.
His recent mid-term opinion is bearish however :

Literally he said "mid-term LOOKS bearish"
Things can change quickly and markets are irrational

Would like to know what he calls mid-term as generally in traditional investments that means something like a couple and even up to 10 years. If he is talking in Bitcoin terms it could perfectly mean a couple months.
Even if masterluc's predictions have proven surprisingly accurate... his wording often reminds to Nostradamus.
