Delayed correlations showing a classic divergence. That low in BTC is important. A chunky break will see the others turn around and offer a low (well lower perhaps) risk of a healthy short sell.
These are how relative value spread trades are born.
Have a look on your other coins for a similar pattern.

Sell or hold ?

@sketchers, maybe think of it this way: which of these would be the better sell? Think path of least resistance and risk. Keep it simple: compare ETH to BTC only. As far as upside risk goes, just a chart eyeball suggests ETH carries less risk given it's already outperformed. So, thinking about scenarios can help:
Scenario: BTC carries on down through that level. ETH is likely to correct also.
Scenario: BTC bangs about and goes nowhere. A short ETH trade should not lose much or anything.
Scenario: Some bloke called Elon sends a tweet and BTC sets course for the moon. All short trades are stuffed then, but given ETC has already had some upside, then perhaps the risk is less.
