you can't expect the volume to increase beyond what it currently is and was in the past week when price rise is still small. in other words when for the past week price has been rising slowly from $3700 to $4000 the volume stays the same as the rate of this rise. if it changes and price goes up faster then you can expect a bigger volume.
Just bet it, win or lose.
sorry but your comment doesn't make any sense to me!
you don't explain why you think bitcoin will "keep going down".
and also what you say about the "mindset" doesn't make much sense either. you either speculate a rise in long term or you don't. if you do them you should be accumulating right now that price is stable and at least close to the bottom not just wait around!
