What is the problem of listing on public exchanges? You collected more than enough money, to afford the listing fees on any exchange. There are no news after the end of ICO. The only news are, that all advisors suddenly disappeared from your website and you stopped any proper communications with investors.
The key reasons for the delay are to finalize support of ERC20 tokens on SpectroCoin, to push hard for the launch of our own exchange, and to audit our contract to be 100% sure it has no flaws. Our contract is unique due to the distribution of net transactional revenue share, so have to make sure it works without issues and our contributors get their weekly revenue shares smoothly.
