XRP co-creator sold millions in 2025, says he hasn't bought the token in years
David Schwartz sold about 2.5 million XRP in 2025, paying $1.7 million in capital gains tax, and says he has not bought the token in years.
Shinobi outlines how a real quantum attack on Bitcoin could unfold on chain and which coins are at risk.
The danger quantum computing poses to Bitcoin has moved beyond abstract theory, and Bitcoin Magazine technical editor Shinobi describes what an on-chain assault might actually entail. He says there would likely be little advance notice, just activity that gradually appears illegitimate, whether a swift seizure of funds on major exchanges and ETFs or a stealthy extraction of Satoshi-era coins moved in increments. In his discussion with Grace Remington and Sean Hagan, he details the actual amounts at risk and how an attacker's goals shape the entire outcome.
