#Bitcoin wallet designers: Do not truncate trailing zeros from the BTC denomination! Always use the same precision! As a user, I need 15 seconds to figure out whether 0.0000089 BTC is 89 sats, 890 sats, or 8900 sats. It would've taken me 10ms if it was 0.00000890 BTC.

Germany, the country I live in, decided to magically create 100 billion Euros to spend on the war. Entirely financed by new debt. They can never raise interest rates. Nobody cares. Our fiat world is in an endless spiral of infinite credit, low interest rates, war, and collapse.

This is the CPU usage of my #Bitcoin node. Whenever a new block is mined, it is validated by every node on the network causing a spike in CPU activity. I love to imagine how the CPUs of tens of thousands of nodes across the globe spike in synchrony with mine.
