Ascending accumulation ranges can often be mistaken with bear-flags, due to their nature, of travelling in a channel.

They are a sign of an increased demand as buyers are not letting price drop further and sellers are already exhausted enough.
They are strong expansionary setups and if not spotted soon, you can get hurt trying to short them.
I'm writing this because altcoins are showing some early signs of that. I'd wait about jumping to conclusion that this is a bear-flag that breaks down further.
