The only trendline investors look at (as opposed to traders) is the five year exponential trendline, which has leveled off. 

1.There is no possibility of a new ATH without an increase in max block size.

2. There is no possibility of an increase in max blocksize with bigblockers split between Classic (BIP102), XT (BIP101), and Bitcoin Unlimited.

3. There is enough Fear Uncertainty and Doubt to prevent ANY scaling solution, including SegWit, before the Network hit the Transaction capacity limit.

THEREFOR: We will hit the limit and have a network congestion failure. The price will crash. It is almost inevitable now.  The only question is when. My best guess is two months.

THEREFOR we are fucked.
