I see another aspect of this query too. Maybe he and many people want to know if there are any big stores like eBay that accept crypto payments etc ? Is their stores like Amazon but accepting bitcoin? I don't think any store of that scale exists that accept crypto.

Either these stores like eBay and Amazon start to accept Bitcoin payment directly or we need new big stores where Bitcoin payment is accessible. This may not only ease the online shopping for many people worldwide and will also act as a source of Bitcoin adoption globally.
