Re: What will happen to alts if Bitcoin crashes back to $5000?
I don't think many alts would recover against Bitcoin if this happens and so they will crash even more. Some solid alts with good liquidity like Litecoin may recover but most won't recover in my opinion. Thoughts? 
I think its not all altcoins will crash if bitcoin goes down on $5000 maybe some will goes down too but some will gonna be rise. Because in my experience i saw some altcoins goes up when the bitcoin down and some goes down when bitcoin goes up.
So it depend to the investor.
