A trader known for making $197 million by shorting the crypto market during major downturns has reportedly flipped bullish on select altcoins, opening high-leverage long positions. The move has drawn attention across crypto circles, as it signals a potential shift in market sentiment after months of volatility. While the trader has a reputation for timing major trends, analysts caution that leveraged bets carry significant risk, especially in an uncertain macro environment where sudden price swings remain common.
