long time ago in bitcointalk forum, there are 'crowdfunding'. you can't call it 'ICO/IEO' etc, it should be crowdfunding. why? cause the organisation didn't give profit, and non-profit organisation didn't have any investor, only donator that spent their money.
but, under non-profit organisation, possible to build a company or something like that, with that you can do 'ICO/IEO'.
back to crypto, what you will do with your 'currencies'? what you want to do with blockchain in your organisation? can you explain about usecase of the blockchain in organisation?
For the mean time, I am not sure that we have people that cares about that now, everyone you see here is going to donate into something that would give them profit, and for a nonprofit organization, to me it is more of a charity organization and the I think Binance is running something of such, but the reason why Binance could get donation is probably because they have been known and trusted.
In this age where everyone is seeing every project as scam until proven otherwise, the vision of the op might not be a realistic one, better he does what others are doing to raise more, have a project with product that will give it a real use case and then use IEO to fund the project that can give such investors benefit along with his donations to him.
