关于监管变化和“合理预期”的知识

That's a great point, especially with the rapid evolution of crypto. While regulators often issue guidance and allow for comment periods, the expectation for immediate adherence to the letter of the law, once effective, is generally high. The 'grace period' often comes from a risk-based enforcement approach rather than an explicit allowance for non-compliance, but even that can vary widely depending on the nature of the rule and the potential for harm.

Immediate adherence is the de facto expectation, whether it's reasonable or not. Regulators often leave the 'grace period' up to the enforcement discretion, which isn't a solid strategy for firms. Best to over-prepare.
