I am always checking every single detail that I can find about the people behind the project. The crucial thing is to see how much is the developing team committed to the idea and it is easily shown by checking all the alterations, changes and updates that are done in a certain period of time. The improvement has to be constant so that you can be sure that it is not a scam project where they are only looking to collect the initial profit. Also, the actions that are taken in promoting and implementing the coin in the market, CMC, exchanges, etc. The project that I am currently interested in and that satisfies all the criteria that I have mentioned and that is important to me is BTCN. This altcoin already reached CMC and is active in a couple of credible exchanges. It shows a steady progress and improvement for now.
