Note that afaics the above purchase agreement guarantees no distribution of dividends to EOS Token investors, from selling EOS Platform tokens. So I have no idea why investors are investing. The section of my blog proposes how to achieve such distributions providing an incentive to investors, without causing the platform tokens to become investment securities.

Yes i wonder the same thing with this form of fund rising based just on buying a token on eth.

Maybe investors have other interest in the development of eos ..
