This is one of the worst bitcoin forks and has no future. Even bitcoin gold is lame but it has a high market cap. The diamond variety sounds good in name, but in this case gold is worth more than diamonds. Although to be honest, you should just stick with bitcoin, these forks will die off eventually
Obviously all bitcoin forks has no future, expect for BCH, because the people behind are really doing their best to really promote this as the real bitcoin. But if not for them, BCH will simply go down die as well together will all the Bitcoin forks. As for the OP, let me give you a good rude awakening:
That is a fork coin and look what happened.
