NFTs or Non-Fungible Tokens are taking off. These 1 of 1 art pieces are stored and traded on the Ethereum blockchain, and are exploding in popularity. The NFT market has expanded ~10X in the past two years to $300M+, and continues to grow daily. I think in the long-run this is a digital part of the art market that will become a larger piece of our economy. Right now the world's art is valued at $1.7T, I believe that will scale rapidly to $10T+ and NFTs are a huge part of that.
