Everyone says index money buys your stock forever. At the one moment that buying is visible, the price no longer moves. We then tested both directions on Bitcoin ETF flows — and only the backward one survived.

If money grows faster than output, where does it go if not into consumption? The question has a good answer. It just isn't the one in the chart everybody posts.

A chimpanzee guessing at random beats educated experts on fact questions — and forecasters on predictions. That's not a punchline but the finding of several of the most-cited studies.

The US Treasury increasingly funds itself with short-dated T-bills. That lowers cost today — and builds rollover risk for tomorrow. A methodical read on the mechanics behind the headlines.

A chart claims to "prove" liquidity leads crypto. The thesis is serious — the chart isn't proof. What it shows, what it doesn't, and how to test it honestly.

zBTC runs, it's multi-chain, the product delivers — and the ZEUS token fell about 98%. How does that fit, and what does the road ahead look like? A sober tokenomics case study.
