I noticed that while Bitcoin is go up with $3200,3300,3400 and 3500: altcoins are dumping? So if Bitcoin will reached 4000 my altcoins will dump more??

So what will happend to my previous altcoin bags from DCR at 15sats, STEEM at .008 , SC at 600sats.. All of them are -50% down. All of them are bought during Bitcoin correction last May-June 2017

Is there any hope from my bags? Should I sell all my altcoins to Bitcoin?

I appreciate any advice. Thank you
