I can not vote, so I will explain my option 3 here. The best is to not do any pre-ICO, because unless you have something huge, it will look scammy. For the exact numbers from the rest, I do not know, I am not a professional.
Thank you for letting me know. I edited the poll and now I think you can vote.
Regarding the pre-ICO, we had the same problem with this, because we know it looks scammy.
But at the same time, we know the product is huge and will disrupt the entertaining business pretty good. Also, we were thinking about making a minimum cap on the ICO itself. If we cannot gather the minimum funds we set up to gather, we will return all money to those who contributed and just use the pre-ICO funds from the investors to fund the development. This I think will boost the confidence that we are not a scam. Also, we are looking into baking milestone-based funding via the contract into the ICO, so that funds we receive are staggered.
Then don't handicap it with a silly ICO.
If you and your team can't trust your project enough to throw your own money into it and fund it then how are you expecting others to trust it enough to give you money?
And if you and your team are not able to fund it, then maybe not start a project that is above your heads or try find investors without giving them premined coins.
No crypto is decentralized - therefore becomes useless - if some people have control over a significant amount of the supply.
Fund your project without ICO/premine and get coins like everyone else by mining or whatever fair method you intend to initially distribute the coins.
