Two crypto companies are proving that when you go virtual, you can do good for those fighting the Covid-19 pandemic on the frontlines while also living a somewhat normal -- yet virtual -- life under lockdown. Decentraland is a decentralized virtual reality platform powered by the Ethereum blockchain, using its own virtual currency called MANA. Users can also buy 3D virtual space within Decentraland called LAND, a non-fungible digital asset maintained in an Ethereum smart contract.
