Who is the owner? And why should we trust the owner not to run away?
This question can be asked about almost any Bitcoin based service and even fiat based business out there.
There are some common best practices that any exchange should follow: from proof of reserves to security and due diligence: KaiserBourse will conform to these guidelines.
There is another best practice. for Traders checking out a new service :
1. Before committing to a large deposit, make a small one, then ask to pull out your deposit.
2. Another thing is deposit only what you want to trade with. then pull out balance when transaction ends. This way you don't have to rely on the Exchange for the long run. just for Ad-hoc trading.
Additional "Trader best practice" suggestions are welcome
