It's a normal thing for altcoins to bleed considering the fact that they all depend on bitcoin so the moment bitcoin struggle they are bound to struggle too
Well, I think that's not true because altcoins having their own value and their own importance so we should not bound them both. According to my analyzation crypto is volatile by nature so it will surely move up and down while we should only invest at cheap price and hold with patience until the price gets better again if the market is down so we should hold and wait instead of being worry.
We can judge a certain coin based on its short term movement, true its volatile by nature but there should be a range where we can call it a good price still.
But, if like for example, ETH from $1K+ drop to $100+, it will not make investors happy even if we convince them that its only due to volatility.
if we look at the big picture, it's not a good movement.
