Preev is down! where do you check Bitcoin prices?
May be check my signature space. 
Your domain is : https://100bit.co.in/
User examplens's domain is https://preev.net/
Both have same interface but different logo, different site title and additionally you have the Twitter linked to you. Who is copying whom ? LOL
I am guessing there are ready made themes already exists for this type of sites and you both got them from the marketplace?

Base on the updated date of the domain, 100bit update there domain first before preev.net which means they might be the first to use it. But you have a point that this kind of format is available in public marketplace which means who is first doesn’t anymore if this software is for sale publicly.
