Among the factors discussed, I pick law to be very important and relating to the topic . Law comes first above the last factor which is risk. Risk is talking about trust and trusting the team or project but I don't even need to trust when I can legally make the team pay for their omission/act, conspiracy, embezzlement and fraud. I just sue them 
Well every investment take risk not only ICO and we have to take chance in order to get success. We have to take step and manage the risk. Anything is possible in business.
