@CaptainCrypto33 @ForestNanoo Sort of correct. The cost is important to have to keep Bitcoin safe. But the cost doesn’t strictly have to be electricity. Imagine if you can have Bitcoin mining powered by manual labor that cannot be automated. That’s arguably better because it makes it even harder to attack.
@船长Crypto33@Forestnano有点正确。为了保证比特币的安全，成本非常重要。但严格来说，成本并不一定是电费。想象一下，如果你能用无法自动化的人工开采比特币。这可以说更好，因为它使攻击更加困难。
