While I love hearing about these really bullish predictions because they make us all feel good, we also have to look at the other side too.
In a recent newsletter by CEO of Bitmex they said:
"The Bitcoin price volatility is the gateway drug into the ecosystem. The media writes about things that move; therefore no movement, no coverage. The diehard traders and engineers will always hear about a new asset class or technology in advance of popular media outlet coverage."

Basically, BTC (and cryptos in general) have been bouncing around in a narrow range for a long time. Traders can pick off their 10-15% every few weeks, but this kind of narrow band oscillation is not what many of the people who joined crypto in late 2017 came for. They came for the 3-4 digit price surges. Without these kinds of surges, the crypto market is just nothing to write home about and with no excitement, there's no hype - no hype = no price surge.
And then cash settled BTC futures are not helping the bull case either, let's see if Bakkt with BTC physical delivery futures can right the wrongs of the past 9+ months.
Yes though if you zoom out a bit on Arthur Hayes's comments (CEO of Bitmex), he also says that he thinks bitcoin will make new highs in 2019. Basically he is just saying we might have more crash before you buy the dip.
