Why what happened..whats going on can't understand...how fast is alt coins downward..worried about losses too much

any hope for coming days??
Volatility and decentralization,only newbies are being affected by this,because those members that has been around for years knows that thisis a normal scenario when talking about crypto capabilities ..for how many times that we've been here we cant count how many situations like this happens and yet bitcoin stands strong together with altcoins
