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? 
\Bitcoin at $5000 is going to produce a purge, those altcoins that just pump and dumps and altcoins that are duplicate of existing projects and altcoins that are not good in marketing their coin and updating their community will suffer if Bitcoin drops back to $5000.
The one thing that keeps these altcoins from being purge from the market, is because Bitcoin is still going up, the trust is still there and they partake of this trust from investors.
You are absolutely right here! Reputed altcoins will recover with the Bitcoin. In every Bitcoin pumps, all the altcoins with unique models and higher trading volume pumped too! Because without altcoins Bitcoin alone can't get mass adoption! So, if Bitcoin breaks 5000$, altcoins will go to down! But those altcoins with Classic, Gold, Diamond extension in their copied name will down to die!
