In fact, this is a good strategy, while ETH guys code and develop core, Expanse team can create dApps and expand the infrastructure, so Expanse has 2 teams - 1 ETH and 1 EXP.

Facts. It's a really good strategy only a small dicked loser would think otherwise. The Expanse team can focus on what the platform can do rather than building the platform. Expanse is also the first eth fork to modify their proof of work algorithm, defuse the difficulty bomb, remove the canary in the mine, and reduce the amount of uncles. They are also working on master nodes, cross chain tx's and dark transactions.
