You can launch an Ico but using only one platform because if you launch and it is two platform you will have a problem on it .I think you and your Team is not capable to run an Ico for now , you haven't not enough knowledge about platforms and you need a capital not only to launch and start all your funds in the investors.
Actually there were ICOs held at two platforms simultaneously. I can remember now of Encryptotel, but there definitely were more of them.
But that is not what I am talking about. I am talking about holding pre-ICO at Waves because it does not require any technical knowledge and coding. And after pre-ICO switch to Ethereum and exchange the tokens from one blockchain to another. Thus, ICO won't be held at two platforms.
As for the comment, that we are not capable of running ICO now, well, probably that is right. That is why we want to hold pre-ICO first and invest the funds raised in ICO, hire a Solidity coder and technical advisors. As for the marketing of ICO, we are able to do that - we have a HUGE experience in that.
