Actually what happened to the market and BTC now? then what about the Altcoin situation that also follows a graph that continues to decline.
I think I have to stay calm for a while and spend time with my family at home.

The decline of altcoins which is almost identical with that of bitcoin is normally because altcoins price is paired with bitcoin's market price. So it makes sense if altcoins' market price tends to follow bitcoin's price movement.
