As far as I can tell, absolutely nothing except for the fact that they want to let Etheruem make the first move making innovations then copy whatever works out for them. The only thing that I've seen people trying to sell this coin as is "like ETH but without a hard fork". This just doesn't cut it for me. ETH is already tried and tested and proven to be king. UBQ just seems to be as useless as ETC, where it has all the same functionality as ETH, but almost nobody that actually uses it. So it's price is simply driven by speculators who see it as a cheap Etheruem.
