I think BTC is rolling over. The rest of ALT CCs are to follow.
With the introduction of BTC futures, the Institutional Money got the tools to take BTC wherever it wants to and the common perception that CCs have the only way to the upside from now on may well change.
Please bear in mind that the Wall Street makes as much on the way down as on the way up.
