Just because the volume right now is lesser than the one it had last week,doesn't mean you should go ahead and short bitcoin, you could lose your money in the process, majority are longing only a few are shorting, you know majority always wins, for your own good don't think of shorting bitcoin instead buy the dips, it dipped to $44k if you bought buy then you would be having some profits now cuz bitcoin has bounced back it's trading over $48k+ now.
