I don't know about down, but it will certainly continue to fluctuate. There are opportunist who get in and out at little 2-5% moves, and there are skittish investors who flinch every time a government agency remotely hints at regulation or involvement. That said, I think you should allow for a degree of movement, and treat $10,000 as a consensus floor - a kinda safety net, that the value should bounce back off of (internally, you should have a plan if it dives through that point). January is always a rough year for crypto, so don't be too alarmed, next month will be a better estimate of bitcoin's direction over the next period.
