I am in the process of building a token exchange platform and trying to figure out if Wix is the right tool. The platform will have three main components: 1) Signup/Login capability, 2) pages to display content (accessible to members and non-members), 3) a form for members to place token orders (sell or buy). Wix seem super user friendly, which explains my interest but before knowing if it's the right tool, there are a couple of questions I'd like to be able to answer:
1) How secure are Wix's servers and is it safe to handle sensible member information?
2) Can the form that will handle the token orders be responsive to user input based on the preferences set by Admin to a certain profile. For example, if I want to apply an order ceiling on a new member's profile, can the form reject the order and display an error message if the member tries to place an order that is over the maximum limit.
One last question that is not mandatory but would be good to know, can a two-factor authentication be applied for member login?
