The bad news was released right at the weekend, the time when the market has the lowest liquidity, so even if BTC recovers, altcoins will not have the liquidity to increase. That's an example, but BTC does not recover too strongly.
BTC.d is sky high, so BTC only needs to fluctuate a few hundred to 1k in price for altcoins to breathe enough oxygen, so be careful Long Short altcoin brothers.
Happy weekend!
