lol It's common sense

if you see a coin that is popular and has had one or two good volume pumps in the past, like cloak for instance
and that coin has lost 90% or more of its value and is being accumulated, then that coin is getting ready for the pump

so it is literally impossible to see a coin lose more than 100% in value which lets the bottom become more visible and easy to buy

coins don't just get delisted out of the blue there has to be several days of looow / no volume, so common sense would lead you into avoiding coins like this

where there isn't a lack of volume, there is either accumulation or distribution that is the "rhythm" that you were referring to there
