I have never heard of the DIM before. These days the ICOs which get more hype in the beginning are the ones which are able to make it to the top later. We can take the example of Electroneum, EOS, ADA which received more hype in their ICO stage and are moving very well now. The current market is bearish and while most of the cryptocurrencies are falling , these are holding it quite well. So I would advise you to take pretty good time to do a research about the coin/token you are going to invest in because you are planning on to invest in it for a long term.
DIM ICO launched last year around June/July and it was successful, I knew about it some weeks backs and read about it since it looked very interesting, and it seemed to have massive potential in the sense that its not just a coin but a complete ecosystem which I want to be part of. You can read more on their website here:
