Bitcoin miner Riot Platforms sells 4,300 BTC to fund AI data center expansion ($BTC, $RIOT)

Riot Platforms' reported sale of 4,300 BTC to fund AI data-center buildout signals miners may monetize treasury holdings to finance capex and diversify revenues. The flow adds near-term spot supply and reinforces the link between mining economics, corporate funding needs, and BTC market liquidity. It also highlights capital reallocation from pure mining exposure toward AI infrastructure, potentially affecting sector positioning and sentiment.
