Can crypto exchanges be listed without SEC approvals?

Could you elaborate on the possibility of cryptocurrency exchanges being listed on financial markets without obtaining approvals from the Securities and Exchange Commission (SEC)? Do these exchanges face any legal or regulatory hurdles in pursuing such a listing? Are there any examples of successful listings without SEC approvals, and if so, what conditions or exemptions may have applied? Is there a growing trend among exchanges to seek alternative listing routes, bypassing traditional SEC approvals?
