Have u considered other platforms? Why have u chosen ETH as a basis for your ICO? What about other options like Waves or EOS?
This is just my opinion. Waves, in my opinion about anything .. EOS is strong, but very difficult for ordinary people. Have you installed their wallet yourself? ETH is the easiest known and most in demand. If he made the recovery of the wallet with forgotten passwords, then I think it would be the very thing that is necessary for ordinary users. This is very important if attracting large investments.
