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?

Most of the altcoins follow bitcoin and if the price crash of btc to $5000 or even lower then we will see bloodbath in altcoin market as we have seen in past two years and most of the new altcoins will be wiped out from the market in such conditions.But be positive on such matters as the whole market will suffer huge losses and its hard to rise again.
