The high-leverage cryptocurrency trader known as James Wynn has once again found himself in the spotlight after suffering another severe loss. His much-hyped return to trading, which he described as a comeback “with a vengeance,” ended abruptly when his positions, worth about $4.8 million, were liquidated just a day after opening them. The latest episode adds to a long pattern of high-risk trades that have repeatedly gone against him, reinforcing the notion that Bitcoin trading is no place for the faint-hearted.
