Will bitcoin continue to fall to $ 6,000$-5,000$?Yesterday bitcoin has fallen below 10,000$. Today bitcoin continues to fall deep down to 8,200$ and possibly more.
I bought bitcoin at 15,000$. Who can advise me to keep or sell bitcoin at this time? Will bitcoin continue to fall to 6,000$-5,000$? what should I do? please..

That was 50% loss. You should set your cut loss bro and yes there is a high possibility that it will go down to 5k cause almost all of the news today about bitcoin is negative so the the market will react to those news accordingly. I suggest you hold it for now cause your loss is so big.
