One recent example

$36 billion looked huge. One wallet made almost all of it.

Headline$36B

Swaps recorded on Robinhood Chain in one day.

ConcentrationMore than 93%

Share of those swaps made by one wallet.

What happenedBack and forth

The wallet mostly bought and then sold the same thing back. Very little money actually changed hands.

Plain answerReal swaps. Little real trading.

The chain counted the swaps correctly. But the $36 billion made trading look far bigger than it was.
