Volume signal: We are still far from the bottom...

We can see the net volume will rise suddenly and sharply if bitcoin reaches a local bottom. So it will be a good opportunity for us to purchase if the net volume soars. However, we still don't see any volume signal telling us to buy.

What is more, I found that the net volume since November is decreasing (shown as arrows. Does it mean a weakening buying power of speculators?

I am quite pessimistic and I think that the selling power of bears haven't been released yet, which means we may face another round of dump in the following weeks.
