Despite all the bullshit and hype surrounding them, they represent the biggest leap forward in building a fair, diverse and trustless marketplace for artists with no gatekeepers. A future where artists and musicians are compensated properly for their work.
I've been minting NFTs on the ultra-low-emission blockchain Tezos since the beginning of this year and have enjoyed having another creative outlet for more abstract work.
