We can expect that bitcoin will soon drop to around $ 6k8 this week or even a few more days. The seller is very strong and it is showing on long, bearded candles. This shows that the market is about to face a bright red and soon investors will sell bitcoins for Tet holidays. so avoid trading during this time period.
It dropped lower than that but the confidence is getting lower and lower because we seem to expect a drop is about to come. I would say that we must be optimistic at these times after the drop that we've seen. Everyone can monitor the market and see if it's the right time to buy after expecting a huge drop. But if you are not confident of trading at these times and you see it as a wrong timing, you should've just hold a little longer and expect a rise would follow after that expected drop.
