Is 35 BtC still your minimum goal? What can you deliver with that amount?
What is the minimum amount required for successful ICO?
The minimum amount whereby the ICO is to be held - 35 BTC, otherwise all funds will be returned to investors.
What can you construct with that amount?

35 BTC is a minimum amount. But our main goal isn't to attract 35btc, but $800 000. The amount of 35 BTC could allow us to hire a few people for cold-calls of data-base. With a amount of $800 000 we plan to use other already tested ways of attracting customers. That's won't be stupid advertisement, which is super expensive in USA, but we could get our client from social network and from small towns. We don't need to pay for site development, because we already cope with that, and it will be finished in the nearest future, no matter what result of ICO will be.
