Don't let yourself being tricked about the real limited information of most slowly updated exchanges. Btcdo is an exchange formerly developed in Hong Kong, but coming from unknown providers that today are no longer publicly available. They can't be reached through any social media link as they suspended all theirs services, and in the case of the platform the access was denied. Now, if users try to find for the site, the URL won't offer entrance.
You can't apply for this option as you already know it is not beneficial for you. Anyway, considering the long list of scam products and projects there exist out there, it is important to mark this one as another difficult place of investments. Take control over your actions.
The important thing is that due to the current suspension of services, inexperienced users can bet their assets in the page.
