In addition, that down-trending channel can also be drawn as a descending wedge if you draw the lines a _bit_ differently. That said, I've already had two descending wedge formations I was considering broken in the past few days, so I'm a little skeptical of them because it doesn't really seem like a high possibility at this point, but depending on BTC and the run-up to October 25th, it's definitely a possibility to look for, in which case you could set targets as low as ~18-21.
