Yes, all contributors wallets (addresses) will be stored in the blockchain.
I think at this moment 20% of profit is not a very attractive deal if people provide 100% of capital in your project. There are many project that distribute 100% of profit among token holders (founders keep some percentage of tokens to get their share).
Good luck with your project!
Actually I ment that 20% of a total companies profit = 100M tokens will be distributed. So according to the number of tokens you will detain, system will calculate percentage of the profit you will get, so each single token will gain a revenue. Does it still make sense?
You would need a big advertising budget to promote the ICO and some dedicated team of developers.
If your ICO is about a physical product or products,i don`t think that many cryptocurrency users would support it.Those type of projects is really difficult to complete without proper organization and plan.
I can imagine how difficult it should be, I have quite good experience in online marketing for physical products so I think the ICO advertising should not be very different. I saw a lot of platforms all over the internet that propose to promote your campaign for success fees as well as for a fixed cost.
I was thinking to make a very basic token so should I still keep in mind to keep a developer in a constant basis?
