Saturday Night Live host and billionaire Elon Musk tweeted Wednesday that Tesla would no longer accept Bitcoin as payments for its cars because he is concerned about the environmental impacts associated with Bitcoin. Tesla famously has a large position in Bitcoin and sold $272 million worth of Bitcoin in Q1 of this year, from which it netted $101 million in profits.

“We are concerned about rapidly increasing use of fossil fuels for Bitcoin mining and transactions, especially coal, which has the worst emissions of any fuel,” Musk tweeted. “Cryptocurrency is a good idea on many levels and we believe it has a promising future, but this cannot come at great cost to the environment.”
