Well actually 70% of our traffic is free traffic that comes from coin communities such as this one, we chose to also have a certain budget for payed advertising, but that doesn't make it a moneypit, this is something that we were going to calculate and the future owner should as well, if an ad is ROI you keep it otherwise you don't renew it. Either way, current ads are all payed for and come with the sale.

About volume, I am not going to sugarcoat it, our volume is very low. But our sale price is priced accordingly low as well, I am not making any profit by this sale, so I'm not trying to "fool" anyone here. We either find someone to take it over or we will close it down.

To increase volume, the truth is that after 1 month in operation you can't expect more then what we currently have. Having 1700+ users deposited and trading on a bugfree platform, even if it's for satoshis, is an okay result for our first month.
I suspect it will take between 3-6 months to get to a point of decent volume. That is at least how long approx. other exchanges before us took (I monitored this a lot over the last 6 months).

We have had several days with volume nearing 4-5 BTC, a few even were we got to 10 BTC (certain coin launches and days when there was general a high volume on exchanges, basically when coin markets are bullish trading traffic increases/when bearish they drop). The total volume on the front page, if that is your source, resets every day.
