i was surprised to see the market today, everything fell in a short time, bitcoin fell around $1000 very fast and looking at coinmarketcap, all coins are red. a few days ago bitcoin rose slowly, but today was very surprising. What happen today?

This is the situation when the bearish market is still running when bad news comes,
all cryptocurrencies Bitcoin or altcoins experience a dump, even though the bad news comes on only one coin,
that is about the BNB and SEC issues, so hopefully this dump will be the last dump in June.
