It sounds to me like your problem is you are looking at garbage that you aren't confident will go back up again...
Heck even bitcoin itself is at a great buying opportunity still too.

They just went through pumps, right now they are in the down phase where they are selling to more and more and more lowball and lowerball and lowerball offers, in other words the stock up on coins ready to sell at the next pump phase phase.
If they were going to pump real soon now you wouldn't have time to stockpile a bunch cheap, instead you'd be in effect pumping them just in the process of stocking up ready for a pump.
Fill the buy side lower and lower and lower so you'll get coins cheaper and cheaper and cheaper while they go down, otherwise you'll end up having to actually jump the spread and buy, driving price up, instead of getting to lurk with lowball offers picking up coins cheap without driving the price up prematurely.
