I do not see a big problem in the fact that price may drop again for some $500 or maybe even $1000. We recently had $9100 and a quick dump to $8500, so a similar situation could happen again. We are in a time when everything is possible, but bulls generally prevail in the last 30-40 days which is very easy to see if you check price just the week before Christmas. I saw somewhere that this was the best January for BTC since 2012, and I believe this is just warming up for one very successful year.
There will probably be many more small dumps, but only because a stable price does not make a profit for those who trade on a daily basis - buy low, sell high, make a profit and repeat everything again.
It's really difficult to guess at this moment. But I think that there are two things that are very likely to happen:
1. In ""long"" term, by the end of the year, btc will be higher than now
2. At 10k will be a correction. The question is how big it's going to be, maybe insignificant, maybe moderate. Doesn't seem that a big one coming.
So buying now thinking in holding for a year or two is a good and probably profitable option regardless of what happens now-short term.
In the short term is difficult to know if it's a good entry price, not going back below 9k again after hitting 10k, or a bad entry price because we could see correcting to 8,5k in a week. It went +30% in just weeks, so a 15% correction wouldn't be a bad thing or something to worry about. In fact it would recover part of it very rapidly I bet.
Edit: Obviously these are just my thoughts, and even though I fell pretty confident about it the current situation is quite difficult to read
