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?
If the token is a new one in the market as has a good team with working product then maybe I will but generally, it is a big risk because the outcome is usually not a profitable one. Low volume may directly signify low interest
