Just requested one... Haven't read much about flexcoin yet but what ensures it's security over any other escrow service?
Everything is encrypted with high grade encryption, salted.. etc etc.. Comodo "green bar" SSL, firewalled... We had it audited by a bank auditing company. It exceeds banking compliance standards. The main site is just a standard http .. the banking area (on a differing server cluster) goes to the secure system.
Is it foolproof? No.
Many of you guys know the only "100% secure system" is one that is physically unplugged and turned off... and like any website on earth it can be brought down by DDOS attack.... but it does exceed what many would consider "normal security" or even "high grade security".
And how do you guys make your money? I read the FAQ, but haven't found anything about fees yet.
