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?
Always see the project,development team,core idea,community response.If all of these features are found in a particular token then buy that token and hold it.It may be undervalue at that time but with increasing community response its value may increase tremendously.Always select the best project based token.
