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?
This happens when someone wants to make a pamp and make money on it. As a rule, this is done with tokens with a small volume of output and trades. Initially, a frantic growth is created, which is of interest to hamsters, they think that growth will continue - they rush to buy this token and then they are poured on the full cheeks of these tokens. As a result, hamsters are left with nothing.
