Don't confuse NFT gambling with Bitcoin. The former is a dying craze as the gamblers move onto something else. The latter is at all-time-highs, for the obvious reason that a digital replacement for gold is clearly useful, and Bitcoin is the obvious leader in that market category.

Indeed, for certain use-cases Bitcoin is competing with Christies too: a lot of the fine art market is actually about storing and moving value. Not about the art.
