What I see from this situation is that although the prices are probably not going to go up on a grand scale. There may be small rebounds after dumps, but they don't really matter or change the bearish trend anyways.
However, I think that we may have saw the temporary end to this dump. The entire week has been bearish, and the bottom was near. It could be possible that the $6k bottom held its ground, and BTC is now on its way up for a rebound temporarily.
If you're looking to sell, wait for price to recover to around $7.7-7.8k in the short term before selling. If you're a long term holder, investing now wouldn't be a bad idea since you're literally getting a discount of 60-70% from last December when everyone was saying to invest in BTC for the long term.
I wouldn't like the idea of small rebounds as in the long term perspective it will still go down. This bounce plays are technically for people who are into buying and selling in the dips as they are looking for accumulating more Bitcoin in the process. But if this will continue in the long term I don't think Bitcoin will recover in 2018. 5900$ might not be our lowest point for 2018 if this trend will continue, right now the market is bearish overall and that possibility is strong.
