$30 million is not that big if you compare it to MobileGo's ICO, also a coin for gaming (mobile), which was able to raise $54 million. Also it is just the limit, the coin will be used and developed even if the ICO will not reach its maximum funding. And if you are doubting and that they will run away with your money, try to visit/research the projects that they have already done. Maybe you can decide it after, whether to trust them or not.
