Bitcoin surged to an all-time high after Tesla Inc. said it's invested $1.5 billion, becoming the biggest company yet to back the controversial cryptocurrency.

Bitcoin jumped as much as 15% after Tesla made the disclosure in a regulatory filing, with prices exceeding $44,000 for the first time. Tesla also said it would begin accepting the digital token as a form of payment for its electric cars.
That Tesla, one of the world's most influential companies, and billionaire Elon Musk have thrown their weight behind Bitcoin is a massive sign of support for the cryptocurrency, which has been criticized by policymakers for facilitating money laundering and fraud.
