Not every single altcoin is bad, but the general picture of altcoins is depressing. ETH cannot overcome 160 mark for months, LTC, EOS, DASH are swimming somewhere without any sign of improvement for years.
Yes, indeed not all altcoins are bad, because this month there is also an altcoin that is rising in price, I see it through the bituniverse application that I use on my smartphone, just because most altcoins are falling in price so that what is going up is as if the price is not looks to the public, and makes judgments to all altcoins worse.
