I have no dog in this fight either, but I was doing some research on exchanges so I didnt put all my eggs in one basket.
If you read this thread:
http://forum.bitcoin.org/index.php?topic=17004.0... you will see the guy who runs Bitcoin7 has::
- Tried to bribe a bitcoin developer to say that bitcoin7 was better than mtgox. (reference link)
- Has no idea of the technology his own site uses that inaccurately computes currency values.
- Has no idea of the technology his own site should be using to accurately compute currency values.
- Been told about exploitable areas in his site, just to minimize them when bitcoin community professionals informed him of them.
- Argued with, belittled, and maligned those professionals who tried to help him fix the problems with his site.
- Uses PR gibberish to explain away and minimize problems with his site.
- Has lied to the community about seriousness of the flaws in his site/security.
Personally, by his own words, I think the guy is a dickhead, bullshit artist, PR person, has no clue about the working of his own site, who will say anything and do anything regardless of ethics and legality to add fake legitimacy to Bitcoin7.
When dealing with other peoples hard earned money, you take it seriously.
Your customers safety, security, and money should be the absolute most important things.
In my opinion, he could care less about you and will step on your neck if needed to grow his fledgeling Bitcoin7 business.
