Added $FUZZY Trust Line, Not an Endorsement

As I promised, I have added a trust line for $FUZZY. This is not an endorsement of the project in any way. I know *much* less about this project than you probably think. But I do think it's a fun community. https://t.co/vU1nmhMML7

Own Your Mistake: Verify L2 Details Before Posting

I deleted some incorrect posts of mine that were based on me confusing Arbitrum with a different type of L2. I should have done a few seconds of research and apologize to @monerify and @dario_nakamoto for the noise and confusion....

Doubts Over Collateral May Trigger Broad Asset Haircut

An asset is not fully collateralized if there's serious doubts whether the supposed backing will actually be used to back the asset, and I think an across the board haircut is not unlikely.

9th Circuit Holds Amazon Liable for Selling Suicide Kits

This article is complete garbage. It claims that the symbol is not protected by the First Amendment because it is incitement, but neither mentions the relevant legal test nor presents any argument or evidence necessary to satisfy the test. The test...
