What counts as success in equity crowdfunding? Investors need to know what they can expect. Startup investing can be a long process, with multiple stages. The company may have no revenue, so it won't be paying dividends.
It will be a long before the shares are listed on any exchange, or an over-the-counter market (OTC), so your investment will be 'not readily realisable.' (That's the regulator's jargon for saying that you're stuck with it, and you'll be lucky if you can find a buyer.)
