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?
Not all low priced tokens are safe for long term investment. It is best to use the high prices coins which are already very stable as you will be more sure of their future survival or relevance.
It is necessary to carry out an economic analysis of a coin with a small capitalization and this will be a very good investment.
