Segwitt + halving + lightning network or other sidechains + those other bullish news from the pas 1-2 years. All of that wil trigger a new massive bull run.
i think these things are not priced in properly
with the classic vs core war that had been ( and i guess continues to ) playing out.
poeple are not so much pricing in Segwitt and LN as they are pricing in the bearish classic vs core war thing.
ex. when mike herrin rage quit saying" bitcoin is busted " that was a pretty big blow, there have been many many drops caused by this big block vs small block thing.
despite this "war" market has managed to keep its head above the water.
I really dont think the positive effects segwit +LN will have on the network have been considered by market.
once we see segwit get adopted and sundly blocks aren't crazy full anymore and useful applications of LN start being used ( ex payment channels creating an instant way to transfer bitcoin to and from all exchanges? )
we're going to have a MASSIVE bump, possibly break ATH, and fly away.
