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..

yes... i guess $5000 is and ideal price for BTC, I also bought some when it was $15,000 but I had some fraction when it was below 8k. Well I'm keeping it.
Why? Reason is you will need it later for any ICO or if you decide to buy any other crypto currency.
