Kraken co-founder Jesse Powell has lashed out at the Securities and Exchange Commission after it sued his crypto exchange for alleged securities law violations.

In a Nov. 21 post to X (formerly Twitter), Powell called the regulator “USA’s top decel” — a term used in tech circles to insult someone who slows progress — and claimed the SEC wasn’t satisfied with the $30 million it levied from Kraken as a settlement in February.
