Sometimes the price goes up, sometimes the price goes down.

1. It's really hard to know where the price will go in the short term . Drawing lines on graphs may not actually help too much. The forces of supply and demand set the price of bitcoin. The best bet is really to do some type of sentiment analysis.
2. Considering it is sentiment that drives the price, putting out a "btc emergency" post can be self fulfilling. For some, you could be instilling Fear/Uncertainty/Doubt into people, hence increasing supply (those wanting to dump btc) and decreasing demand ( those wanting to buy at a given price point ).

However I do respect your want to warn people (in hope that it's ernest) .
