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? 
Only major altcoin (top 15 CMC) will survive and another altcoin will be dumped sharply in the market.
Remember this scheme:
If BTC Pumping, Altcoin Will stay
If BTC Dumped, Altcoin will dump
If BTC Stable, Altcoin will pump
