Every single Bitcoin that is being paid to miners for Ordinals transactions is enhancing Bitcoin’s security.
Those new fees incentivize more miners to join the network, further strengthening the security of the blockchain.
If the incentives for mining Bitcoin fall away, Bitcoin could be in major trouble. The less mining power on the network, the less secure it is. Saylor also likely appreciates Ordinals for the massive amount of functionality it gives to Bitcoin.
Much of the crypto community expects Ethereum to eventually surpass Bitcoin because there were basically infinitely more use cases. However, now that Bitcoin developers can do many of the same things that Ethereum’s smart contracts enable with Ordinals, the functionality gap is closing fast.
