Unfortunately low volumes coins are good only for speculations because they do not have any practical use.
There are a lot of cryptocurrency exchanges to sell the low volumes coins. Also there are platforms like https://www.qoiniq.com/ that allow to trade different coins on different exchanges at the same time. I think that low volumes coins give a good opportunity to earn money on trading.
This is the reason why many people do not trust cryptocurrency, because it is use only for speculations.
I checked the https://www.qoiniq.com service it allows to make orders from different exchanges at the same time and I think that it is very comfinuent for traders.
