Of course not everything other than bitcoin is a security. My private blockchain no one knows about is not a security. It's not a universal law of the universe.

What they mean is every coin/token they looked at. If asked to evaluate litecoin for example probably they'd say it's not a security as well. They don't need to pass judgement on each of the thousands of coins individually because definitions and common sense exists.

I’m just trying to understand the context. I hope it is as you say and it would be my baseline assumption that it is as well. But it’s not unquestionably obvious given history and what relatively little context is present in this thread. The SEC used to think all crypto is a security to the point where honest miners are instructed to declare blockchain rewards as income (I have, and TurboTax even asks you if you acquired crypto in the last year with no nuance as to how you acquired it). It may be obvious to you and me but my question was more about how far the SEC’s understanding has evolved.

They refuse to offer guidance even on the largest cryptocurrencies outside of BTC.

The same as units in my LLC aren’t. When I sell them, when they’re traded, that’s when they become a security.
