I haven't seen it go that high? Coinbase has it at 9900 and if you google Bitcoin value it says 9913. I am not saying you are wrong just where are you seeing it that hight?
Bitcoin is $10,000 via coinmarketcap. Coinmarketcap sort of averages the prices of bitcoin over multiple exchanges. A good percentage of exchanges are from a korean exchange, whereas the price is already $10,000. Lookup the Bithumb exchange in coinmarketcap BTC page.
