Hi! I heard that there's a game called CryptoKitties where you have to raise these kittens. You must not be talking about? There was a case where someone paid 600 ETH to buy back a collectible kitten. It was estimated that the amount reached almost $2.5 million. Generally, I've noticed that creating digital collectibles is very much in demand right now, shall we say. For example, have you heard of Chainers https://chainers.io/ ? It's a whole meta universe where you can create characters and trade them in.
