I never sold a single NFT. But I was given a free invitation to attend a big crypto conference. How could I say no?

The conference's final event was a big art auction. I sat in the back making friends with the waitstaff serving hors d'oeuvres, and watched as a drawing of a cat sold for $140,000 USD. Apparently it was a CryptoKitty, drawings which had already become coveted like trading cards in the crypto world.
