Green market death and red market start but altcoins still alive. If the altcoins market will death then who here for money spend?. The current market situation very hard so you should invest money for maintain more think. Remember every altcoins will not give you profits so try to invest in right coin then your profits confirm.
I think what you say is true because indeed not all altcoins can provide good profits so everyone always needs to choose the right altcoin in conditions like now, because the decline in all coin prices in the market is not a sign for the death of all coins, but it is a condition where each coin must survive in order to survive as usual.
