It's too early to say right now. I've become more and more blockchain-sceptical over time. Most projects don't seem to me to be solving any real world problems and they aren't doing anything well enough to wrestle users over from traditional centralised systems. There's little to no improvement offered. I think at this point we can see how much the general public cares about "Wow, such decentralization!". The one thing that a handful of cryptocurrencies do do better, is untraceable, unlinkable transactions. So if I were to start work on MOIN 3.0 today, I'd want to incorporate private transactions since to me they're actually useful.
