I had a wild idea before, one that would attract a lot of criticism, but I haven't expressed it yet. Today, a friend in the comment section also mentioned a similar idea: in the future, perhaps ten or several decades from now, BTC may have become the de facto digital gold, worth over a million dollars each. However, BTC's security budget subsidies may no longer be attractive, and miners may not have the motivation to mine (eventually the mine will be depleted). At this time, unless the transaction costs of the BTC ecosystem are sufficient to support the security budget, the incentive system will fail. How to break the deadlock at this moment? There are several options, one of which is to use it as a super digital gold meme to issue BTC of ERC20 on the Ethereum network, and then have Ethereum L1 protect its secure existence. If such a probability really exists, it also means that in many, many years, Ethereum may carry assets worth millions or even trillions of dollars (considering inflation in many years), becoming a de facto public good in human history and a de facto global financial settlement layer.
