UPDATE: 11th June 2019 – Yes. After a community vote earlier in the year it was decided that there would be a 1% burn rate for every parcel of LAND sold on the marketplace.
No. All MANA tokens used to purchase LAND and districts in the Terraform Auction were burned. However, when buying and selling LAND on the marketplace MANA is not burned.
