Why do we need decentralized virtual world if we don't live in a virtual world? I live in real world and don't need Decentraland because I will not use and buy it, useless thing for me.
I don't think you understand this project and also you understand the digital world, why do we need cryptokities, why do we need virtual currencies, why do we need virtual football. I believe Decetraland is one of the few projects on the Ethereum platform that is going to scale up with time, it is surely a long hold
But to created decentralized virtual world does sound make sense for you? The decentralized system doesn't even replace the centralized economic system. This doesn't make sense for me personally.
As far as i know there was a lot of projects are trying to create the platform that based on the non sense idea or innovation.
