It is normal to see fall in prices of coins, we shouldn't be expecting to see increase in the prices of the coins everytime. Whatever direction the winds blow, you should be prepared and ready for it. Always have it in mind that the market might not always go in your favor, but also always hope for the best and make good use of every market situation.
We should be psychologically prepared when participating in this market because this market has no stability and just a small mistake will make you lose a huge amount of money. I think adding knowledge now is something that all investors should do during this period because if you have an understanding of this market you will avoid a lot of risk in investing. I personally read books when the market is on a downward trend because this is a way to reduce my fear.
Unless you see the transfer of large amount of BTC goin to the exchanges, you will be prepared for it. But no one is pretty much prepared when it comes to manipulations like this one. So if they have successfully did drag the price down, they could do it again and they could also push it up to set a bulltrap.
