ICO allocation - You have the rights to a set of digital hashes, that will hopefully rise in value on a coin exchange. You own no equity or voting rights. There is no fiduciary duty to investors, unless mandated by country of incorporation (eg: company can shut down and walk away with the money and you can do nothing, in several cases). Many startups are looking at ICOs to quickly raise funds to avoid the loss of equity and reduce fiduciary liability.
