The 1 million ether cap equals 260 million USD equals 520 USD market cap. It might look big but compare it with Ethereum or Stratis which are much bigger.
It's ironical you not getting the point. Hidden cap and hard cap are two different things. The basic concern that investors have is, why change the terms of contract as written in your whitepaper, that is not only fraudalent, but simple demostrate bancor as a money grab project. Ofcourse i like the vision and what it aim to build, but do not tarnish your image with greed. At the long run the investors are the primarily people who can promote your project, even if it is someone who is investing 1ether. The stratis you just stated, i invested during its ICO for 0.5 btc which was at around 300USD i got 55,000 stratis. Stratis investors are die hard Hodl and that is the basic reason stratis is shooting up and achieveing such success. You cannot at the beginning of your ICO change the terms, because you already got enough VC backing or amazing presale. the image of the company, and the community support is what matters most in this crypto-space and not neccesarily the idea or technology.
On the other hand, the uncapped idea that you choose would give anyone who wants to get in a chance. All the best in your ICO.
