I think there is some uncertainty in the market lately. With all the bitfinex/tether drama and while CME is certainly a great new, it gives the possibility to short the market for the first time, so if an institutional investor bets on the “bubble” popping could easily lead to a huge drop as people lose faith. As Antonopoulos said, another bitcoin bubble could eventually burst...but even Amazon and Apple stocks were in a bubble in the early 2000, look at them now.
