Sometimes, it is not about low value, they might be low in value but have no trade volume and also have no working product that will sustain them in the market for a long time, and these coins are usually products of pump and dump coins because they are easily manipulated, although low trade volume products that are quality could really be profitable when they pump like the ones that op mentioned, they are very affordable and an average person could accumulate as much as possible, and these coins are the once that use to pump naturally like up to 1500 percent during the bull run. So we could still give a try to those ones, but when it comes to sustainability and relying on a viable project, I think we cannot give it to any other coin than the top coins.
