In our case this problem will be solved by the following scenario. As you have mentioned crypto-investors knew that the ICO has some investment from a real-world investor. This fact can be the reason to believe in the project, if the real-word investor has a Big name", if it does not, crypto-investors are free to decide whether or not they want to have tokens of a company that does not wish to disclose information about it's performance and keep the option to return their funds if it's needed
So, to conclude, they're allowed to "cancel" their investment and fully withdraw their funds from the project? Or, will there be some dedducted fee? This company policy of yours somehow has a potent to merge with my next question about KYC, but let's see the answer up to this point
If the Investor decides to return their funds, they will be fully returned based on the initial investment.
