It's suspicious, check out contact page:
https://cointopal.com/contact AFAIK Moriarty is one of scammer, even the site use SSL bit it's not guaranteed if the site trustable.
That site hides its DNS registrar through namesilo.com
The SSL certificate might have been bought anonymously, and namesilo won't disclose who registered the domain if you get scammed. I'd stick to virwox.
