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?
Well, good traders know how to raise the price of a coin. Let's say they bought a large package of tokens on the dump for cheap. Then they just sold it 3 times more expensive. Is this token good? not. It's just a game. Where there are experienced players who can give the price of the coin and there are losers who will buy more and then lose everything.
