Thanks for explanation, I agree.
I think it also depends how you consider "tokens", now many ICO want to sell as many tokens as possible, to earn money.
But if you consider tokens more like shares, so - parts of company - then 30% of course doesn't look a lot.
Good luck with ICO!
Only if you look at the tokens as a stock, 30% is not a large percentage. I think this is quite a normal percentage
