tokens are fine but offering profit-share is illegal, it's like promising dividends of stocks and that shall be regulated, even with digital currency it is illegal up to my knowledge.
how about asking for different % of collateral depending on the assets in the poll?
how would you rate them?
Good point, considering that an asset could be used as either a promissory note of types (i.e. crowdfund profit-share) or a token representing a specific value (i.e. digital goods, physical goods, services, etc.)
