If you really want to buy, it's actually a good price, but I think bitcoin will dump again, and fall to 8000$ in february. Then, the bounce back and will rise to the moon, expecting 20 000$ target and more. So, my advice (for what it costs I'm just a random member), wait few days if you want to buy because it will dump again. Buy now if you think it will not dump more.

If you're in a situation where you've already bought bitcoins, just hold and don't panic, it will probably rise soon.
