I would say Never even if I'am new on Bitcoin ... but I see that it was about 600$ last month ... and it's dropping badly this month 480$-520$ so .. yep 
It's rising, 518$ now. These flucuations are normal in bitcoin. If we have a big rise like in the beginning now, we would end at around 2000$. 10.000$ is far away but I wouldn't say never. At the same time, fiat is suffering from inflation.. so I hope BTC rises faster than fiat inflates
