Thanks for your comments JayJaunGee.
I decided to keep holding as I said.

I am more worried about ethereum, which is a big part of my investment.

I will still holding it, and hope to dump those coins in the first opportunity. If BTC recovers, ethereum will probably reach my average price (something near 250-300).

I believe ethereum is an interesting project, However Vitalik is the problem.  He is like a CEO,  it became his blockchain... Let's see where it goes. If he manages to launch Casper (PoS) it will be a nice achievement for the whole ecosystem (as other POS coins were very centralized and much smaller projects)
