From what we have seen in this dip with Bitcoin is that it has such high correlations for the prices of every other altcoin. My advise for anyone in this space is to pick the coins that you believe in as this will help you have stronger hands to HODL when times get rough.
I don't think it really matters right now in this bearish market what altcoins you invest in as long as the price of Bitcoin eventually goes up :)
Buckle down and HODL whatever altcoins you invest in!
