Related to this valuation: it's a marketplace. Putting aside my thoughts on NFTs themselves, is there data that suggests the marketplace itself provides enough utility to justify the valuation?

Separately, I really do wonder if it's time that places like OpenSea borrow from traditional investment and provide some warning upfront.

For example, modified from the traditional investment verbiage:

> Investments in NFTs: Not FDIC Insured • No Bank Guarantee • May Lose Value. Investing in NFTs involves risks, and there is always the potential of losing money when you invest in NFTs.
