I merely think you've overstated the security of your site as "the most secure". Hard to make that statement without actual proof of 3rd party testing against/compared to other exchanges right?
I coded the whole thing from scratch, including the exchange http server and had 3rd parties test it already, combined with numerous hackers testing it for the 5 months operational. It's never going to be "enough testing" in some people's minds, and it comes back to you simply not liking me boasting about something I personally think is impressive. You are free to have any opinion you want about my security and my claims, I don't judge you on it. And if you don't want to use the exchange due to it then that is your right.
You didn't even address the part about actually comparing security tests between yours and other exchanges. Now if you had done that and a 3rd party (neutral) claimed your site as "the most secure" then fine. But until then, it is just YOUR opinion as opposed to facts that you are advertising to users.
Typical salesman tactics...
