I'm interested in knowing how the website looks exactly the same though? Did you manage to get their source code (including the backend)?
What expertise do you have as well? If you're just former users of BTC-E that doesn't mean much for the average user, people want a professional team.
We are independent IT specialists, we do our own cryptocurrency exchange. We have not received source code, or anything from btc-e/wex. We do write our own backend for the exchange.
About expertise: as we are a group of IT specialists: programming,db-management, security, payment proccessing etc. are not problems for us. Each day we get dDoS attacks, hacker attempts etc. and we successfully mitigate them. As we grow up, each week we do security analyze, and take backups everyday. We understand that owners of btc-e/wex will (or already doing) try to hack or find any security flaws in our systems. but we believe in our professionality and we are ready defend our project.
