this is a pretty good project to build an e-commerce website that supports bitcoin as a payment base. however, there are several things that concern me and maybe you can apply them to your website;

1. you should put prices in usd and bitcoin to make it easier for customers to calculate the price of goods, so they don't need to convert on other websites.
2. information on estimated fees for transactions on goods the user wishes to purchase.
3. payment option using escrow for users who want to be more secure in their transactions.
4. if the escrow option is not provided, users should be given an explanation regarding the security of their deposits/withdrawals.
5. does it support dropshippers?
6. what are the fees for merchants? and protection for them?
7. how are products sent to customers protected? is there a tracking system? and guarantee that goods will be delivered to users?
8. does it support international transactions? and what is the information related to customs, etc.?
9. is there an identity verification system? or do users only need to provide their email?
