Since the launch of the new controversial Bitcoin-based non-fungible token (NFT) protocol Ordinals in mid-December, miners on the largest blockchain have made nearly $600,000 in BTC transaction fees.

According to data from blockchain data platform Dune Analytics, a total of 81,468 Ordinals have been inscribed into the Bitcoin network. This has caused an upsurge in user activity and, as a result, increased the number of non-zero Bitcoin addresses.
