Looks good but you can buy other exchange scripts for just 99 $,maybe hire some php html devs = 100-200 $ for theme changes.
I will buy for 99$
No Demo
I can give you a demo link if you want over private message.
100 usd scripts are totaly backdored and full of bugs.
After seeing the uploaded pictures i must commended you for a job well done but 2 btc is not meant for everybody.
If you can't afford 2 BTC to purchase exchange software, then you probably shouldn't be running an exchange. Properly audited exchange software would be well worth the price.
You are totaly correct.
