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?
Usually buying a low volume token will not profitable for most trader because the liquidity is low too.
But for some holder, it can be profitable because they are buying to hold for long time.
If the project success later they will earn a good income.
