One mistake people make in altcoin is by judging the value via it's current price not knowing that a lot of factors can drive the price of a coin high even if it is not working so much in real life,one of this factors is hype created by the team behind this project, since most action has low trade volume, it would be very easy to manipulate the market. This is why we need to be very careful before investing in a project and make sure we check the real life value of the project and how it would be of great impact in to the crypto community in the future.
