If someone looking these charts from trading point of view than it looking very horrible for altcoins but promising coins will survive and get recover when altcoin will have their time. It is good opportunity to buy on low price than we can multiply our amount in future.
You say it right, but when a coin drops rapidly, it causes a shock, why the price cannot hold. There is no faith in a coin and everyone pours into bitcoin? I can buy coins cheaply, but how long will I have to wait for them to start growing, will it be 1-2 years or 10 years?
