Yes. As long as you register on a legitimate site that has been operating for quite some time and has mostly positive user reviews, then you should have no fear of this matter. When it comes to shady websites that seem like they are only halfway through development and have constant issues with stability and ask for your financial information every opportunity they can, then this should raise a few red flags for you. Obviously, the last thing you want to be doing is sharing your personal information with other users and camgirls on the website, that is never a good idea.
