Bullish Flag or Descending Triangle?

I decided to make this post because I saw that people were arguing about whether this was a bullish flag (pennant) or a descending triangle. A bullish flag is a gradual decline in the price of a stock not budging below a support line which forms the flag. The descending triangle is similar in the gradual decline. However, the price does break below the support signaling the selling off to come of a commodity as seen by the arrow. If you have made profit on bitcoin, I recommend selling.

Note: I do not own bitcoin. This is only a recommendation and you do not have to sell if you feel otherwise.
