All right, that increases their chances of success (it’s not a bunch of different components).
It reminds me a bit of Bitnation in the sense that it offers a number of services built on one platform (they use different blockchains and offer different apps, but I’m not talking about that).
Who knows, maybe one of such apps will become some sort of new Yahoo.
IMHO the biggest question about these non-bitcoin platforms is how long will the underlying blockchain last and be safe.
Do you know how many mining nodes are there on the Nxt network?
