I noticed this phenomenon. Often someone buys up all the proposed tokens with a small amount of trading (for example, look at SMT on hitbtc this night), and after a few days these tokens go up in price very much. Is it worth buying such a token?
I tried to make profit on trading low volume altcoin once, and the results were quite positive until one day that coin lost 50% of its value because of dump, fortunately the price recovered within a week. It's rather risky to trade low-volume altcoins, because of unpredictable pumps and dumps...
