The FCA calls this an &#34;appropriateness assessment&#34;, and it’s supposed to prove you understand how risky and volatile it all is. This is a routine bit of friction that UK stackers will be familiar with.<br/><br/>But last week a thought struck me: what if they made you pass a test before opening an ordinary fiat bank account? Prove you understand where your money actually goes, who legally owns it, and how much of it is really protected?<br/><br/>So I built it! Ironically I expect only bitcoiners will be able to pass it. <br/><br/><a href="https://bennet.org/blog/fca-knowledge-test-fiat-banking/">https://bennet.org/blog/fca-knowledge-test-fiat-banking/</a> 2026-06-22T13:29:58Z https://njump.me/nevent1qqsveyrcp8t3ggsw4h53c6wz8vmncd7rwdcup72425ls5938369ly7qzyqjvdacya6uyxgjs43knympnvj98m7n274hxuq84rq22h7h0v3agwlk6s30 In reply to <a href='/nevent1qqsvz66r9syzt33ss9dw9j037rfa3a5mcwrksy5253strx5n39jz0aqpp4mhxue69uhkummn9ekx7mq72jxjm'>nevent1q…jxjm</a><br/>_________________________<br/><br/>Thanks, that’s really great to hear! 🙏 2026-06-20T11:20:35Z https://njump.me/nevent1qqswsdxms5aelrcu43f9cdqh39p6xc5532kwznj9h7m9amnhwa6tyqqzyqjvdacya6uyxgjs43knympnvj98m7n274hxuq84rq22h7h0v3agw6kv3rn Just published an interactive explainer on the Lightning network ⚡️ It includes a liquidity routing puzzle, which I think is a fun way to grasp the channel liquidity concept.<br/><br/><a href="https://bennet.org/learn/how-lightning-network-actually-works/">https://bennet.org/learn/how-lightning-network-actually-works/</a><br/><br/>As always, comments and shares appreciated.
