Ideal hedge altcoin

[penig]

To start, lets be rational about something, we should not expect 2018 to see similar growth to 2017.  One can hope, and it may happen, but there's no fundamental reason to ensure a repeat performance. Prices may go up a lot, a little, sideways or fall.

So, with this in mind what is likely to be the best hedge for Bitcoin: an altcoin that is likely to follow upward trends but also be resilient to falls, even perform better than Bitcoin should it suffer some significant correction?  I'm thinking this will come from the older established coins, Litecoin, Etherum, Dash, etc that have been around and have a bit of solid core usage independent of Bitcoin value or speculation.
