Do You think which of them is best ecommerce software for creating Online store?
1. Magneto Enterprise
2. Big Commerce
3. Shopify
4. WordPress
5. OS commerce
Sadly I don't know most of the websites you listed there however I know shopify and WordPress , I would suggest you to use WooCommerce because it's famous and known and keeps getting updated also you can accept different types of payments including Bitcoin , but .. if you are looking for huge business then you may wanna hire your own coders and programmers to do that so it looks more professional
