Decentralized Marketplaces: The Best Alternative to eBay & AmazonWhen eBay first launched in 1995 it heralded a revolution in shopping, allowing anybody who could access the internet to buy and sell with other individuals. Suddenly the costs of setting yourself up as a retailer crashed through the floor, whilst consumer choice skyrocketed. It was this peer-to-peer character of eBay which allowed it to flourish through the famous dot com bubble and out the other side.
But under the surface the likes of eBay are just digital versions of traditional business model, for example the auction house. Today, economies of scale have allowed sites like eBay and Amazon to utterly dominate online retail. Yet the peer-to-peer empowerment of the individual which has made them so popular does not extend below the surface. Underneath it all, these sites are little different from the giant retail conglomerate of old. Sellers are often forced to pay high fees which make earning a profit difficult, whilst risking giving away control of their brand – making it difficult for them to break free from the platform in the future. Meanwhile shoppers often do not realize that the products choices on offer are controlled and limited behind the scenes from corporate HQ.
Hope it helps somewhat.
