In 2021 Square and ARK argued that bitcoin miners would be the grid's most flexible customer and speed up solar and wind.

"70% of Altcoins in an Uptrend": Does That Include Yours?
Altcoin breadth tells you how many coins are above their 200-day line, and the answer depends on which coins are counted. Since 2018 the 100 most-traded came out ahead on 72% of days, recently 70% against 40% for all altcoins. Which number applies to the coin you hold?
What Is Metcalfe's Law — and Does It Hold for Bitcoin?

759,000 Holders, and Less Money Behind Each One
The holder count for tokenized equities nearly doubled in thirty days. Value per holder has halved since March. Both are true, and together they say something neither says alone.
The Copper/Gold Ratio: An Overrated Macro Signal for Bitcoin
The copper/gold ratio is sold as a macro and Bitcoin signal. What it actually measures, where it fails, and why a viral "Bitcoin cycle" indicator built on it has look-ahead bias.
Why QT Is Over — and What It Means for US Treasuries
The Fed looks trapped: fight inflation with high rates, or refinance the debt cheaply. But it already resolved part of that bind — by decoupling its tools. A methodical read on what this means for Treasuries.

The "hacked again" reflex is wrong. What the Polymarket case actually shows — and the two places where crypto genuinely is harder.
Option vs. Annuity Machine: Two Ways to Be Invested in the Same AI-Healthcare Sector
"Invested in AI healthcare" can mean two almost opposite things. Two real companies show it: an annuity machine with ~86% recurring revenue — and an option with not a single approved drug. Same label, opposite risk DNA.
