Host a demo. And 30BTC is very high for just source code, you can have a custom site built from scratch for less than half your asking price
Coinano.com was already online from march to august 2014; therefore we will not provide demo Please visit our official archive threads and social communication channels
we have used java (enterprise level java technologies) in coinano.com so the base cost (development) was more than 90 BTC (actual 90 x 325 $ = 29250 $) if you want to buy java based exchange platform source code, 30 BTC is not so high starting price contrary the price is very low
Regards
What if we never saw your site or heard about it until now?
