Thanks Hive account@scan0017! To answer your question about where did the money come from, my understanding is that block.one is a venture capital group that has been around for two or three years. It was put together by Brendan Blumer and his banking buddies in Hong Kong and has a lot of Chinese money behind it. I have heard that they had already raised $100M in Venture capital for this project several months ago, although I am not clear if that is already in the bank. So they already had the money to do it before launching the token, and that's how they were able to blow that kind of money on promotion.

How are they going to earn the money back? I think they plan to VC applications to run on EOS. They are basically building a platform, and planning to use the money from the token to venture fund startups with end user applications to use the platform. For them the platform is the loss-leader. But it will enable them to raise a lot more money for VC projects. It's kind of like a whale came along and decided to build a better Ethereum, and asked Dan Larimer to do it.
