Elon Musk talks a lot about Bitcoin’s carbon footprint. And investors are paying attention, according to a new survey. Musk had initially helped the coin reach new highs. Bitcoin rose 8.5% to $44,790 after Tesla disclosed that it had bought $1.5 billion of Bitcoin in February, and continued to soar until April, when it hit its all-time high of $62,000. Then Musk said his car company would stop accepting Bitcoin, citing environmental concerns. Powerful computers, often powered by coal, use entire countries-worth of electricity to crunch complex sums necessary to process Bitcoin transactions.
