I know...there are smaller marketplaces that people can buy/sell goods via bitcoin, but why a major marketplace is not emerging??
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

1. is the problem in supply side? are sellers worried taking payments via BTC bcas of volatility
2. is there a logistically inefficiency, that smaller sellers can never compete with the likes of amazon
3. is the transaction speed an issue for retail transactions?? major cards payments are done instantly (maybe this speed is needed for impulse purchases

)
Comment below...thanks i'm a newbie here

Few problems I would like to mention here :-
1. Government is not really comfortable in letting cryptocurrencies go that deep in the market .
2. People are worried about buying and selling their stuff with Bitcoins because of its volatility , the transaction fee , inability of Bitcoins to actually go good with small Valued goods.
3. Not many people are willing to buy and sell using Bitcoins , it is used as a investment rather than a currency.
4. We already have a lot of competitive market out there with places like Amazon giving people huge discounts on major products I do not think Bitcoin market will be able to complete with it .
