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..

Just hold your bitcoin for a while, selling at panic will not make you profitable instead it will make you lose your investment. Today, we have seen a good rise and hopefully this will continue. Have more patience in the coming weeks you will get your investment back
The trend has continued and the price has been going up for some time but it is still far away from 15k, the price the op bought his bitcoin, and I have my doubts we are going to see that price for some time holding is a good option but it is not easy or do especially if you have lost so much money already, hopefully this is a lesson for all of us to avoid buying when the price has been skyrocketing for a while.
