I have reviewed the open source code of OpenTrade and am very impressed with Dev to have set up such an exchange at very fast speed over just several months.

I have found the code base does support Google Recaptcha, but it is not enabled at OpenTrade. I think the security is very important for the user and for the exchange itself. two factor, Google Recaptcha all are good.

Please enable Google Recaptcha at OpenTrade exchange so that the security is improved. We have to assume that bots and hackers are attacking all day long.
