Though I am curious what your definition of widespread adoption is. I think it is important that we are realistic about what widespread adoption means in cryptocurrency, especially an altcoin in the current market. I can see a world where my mother uses bitcoin. I cannot see a world my she would use any altcoin, unless a major feature/change/disruption is released of a magnitude 100x what we have already seen from all alts combined, I don't see that changing. I do think there is a very important market for altcoins, much greater than day trading and currency speculation. And it is a market I am invested in, with a very significant amount of my time, and to a lesser extent, money (more if I could afford it). And it is that market I look to when I am considering the widespread adoption of the coin, because realistically widespread adoption in terms of the general public is at the moment still questionable for bitcoin, let alone an altcoin.
