Re: Why there is no Standard Marketplace like Amazon with BTC as payment method??
I know for a fact, there is a huge demand for purchasing of goods with BTC...even users from this forum is enough to give the marketplace a supply chain issue 
Please point us towards this fact.
All the facts I have to hand point towards merchant adoption shrinking for several years and continuing to shrink. The peak of acceptance was probably in 2014 when huge name after huge name announced it and since then they've been quietly shutting down.
Most people who own Bitcoin don't want to spend it. People who don't own Bitcoin will never buy something to buy something.
