You have to watch more careful. Dev was absent some time, but the project continued and is a little bit late.
Using the 70 BTC to get the exchange coded would have been stupid, we will need BTC from the IPO to get bugs fixed, to create more services, for marketing.
If they wanted to scam us, simply explain why they havent taken the 70 BTC and run away? They would have had no reason to get the exchange to beta state then.
The dev fixed also a problem with microcoin short time ago, so hes definately not gone.
ALL your info ist proven wrong and misleading people. Next time you wake up make sure your brain isnt still sleeping when you post.
