The mining company sell-off signal is here again. Riot Platforms just transferred 500 BTC (around $39 million) to NYDIG, confirmed by on-chain data. It's not unusual for mining companies to sell coins regularly to maintain operations, but this isn't an isolated case—TeraWulf also just completed a $1 billion equity financing. BTC is currently fluctuating around 78,000, with significant short-term selling pressure. This week's weak trend isn't without reason.
