It is an warning for those who are holding big amount of Bitcoin for further upward movement. I think BTC have traveled a lot and it is the time to drop for at least 3000$. So investment is yours and profit/loss is also yours. That's why think wisely before taking any step. My suggestion is not to hold big amount. You can hold 1-5 BTC as an investment. Cause other crypto currencies trying to come on the filed of currency war.
This is Just my thinking.
All the best and Good Luck.
