With all the traders gravitating to BTC, it is hard to determine what the new normal is going to be.  Some things causing the price to go down are established traders speaking down on the coin, countries discussing regulation or regional bans, and then just people selling off out of fear or in response to the news.

You can google the latest technical analysis on BTC to see what price levels others are pointing out as areas of support where the price could bounce.
In my opinion, making buys around the 7k range and then again in the 6400-6700 range would put you in good shape with some "cheap" holdings that could grow significantly as soon as the technicals turn bullish again for crypto.

Whatever you do don't go all in at a particular price, keep entering in smaller segments at the various support levels until this thing turns, then it's just sit back and watch what happens..and make money.  Good luck, be patient and nimle.  There are too many companies getting into this space for btc to go to zero.
