If the projects are fairly legit then they will decide to return the funds from the investors. They do this by allocating all the equivalent funds that were invested into their projects and they will refund the amount on the address from where they received the funds so that no can cheat on them. However I started my sentence with one important word and thats "legit". To be frank with you not all of them are so caring to refund the money. Most of them will give some reason and may go dark in the time to come. That is from where the scam starts and we get no choice but to forget about these projects.
