Just because the market is suffering doesn't mean that alt coins are dying... This things have and will always happen. I wont tell you to hodl but always only invest what you are willing to lose and if you believe in a coin then stick to it.
There are still altcoin that survives probably because now altcoin prices have decreased and resulted in many people ask Tanya still hope with the altcoin down, I myself think if altcoin in the near future will be stable again because I see the price of altcoin and the market is green and hopefully fast again stable
