Bitcoin's biggest players include Tesla, Square, Mastercard

Despite its critics, bitcoin has seen a meteoric rise in 2021 as companies have embraced the adoption of digital currencies, prompting them to make their own investments. On Wednesday, the world’s biggest cryptocurrency rallied to over $50,000.

Below is a FOX Business roundup of bitcoin and the cryptocurrency industry's biggest players:

Square

Square announced on Tuesday that it would invest $170 million more in bitcoin as the payment firm "doubles down" on its commitment.

"By us owning bitcoin, our incentives are aligned with skin in the game," Square CEO Jack Dorsey said on a post-earnings conference call with analysts. The company bought 3,318 bitcoins in the fourth quarter, or more than $51,200 per bitcoin, according to Reuters calculations.

The move built on the 4,709 bitcoins bought in October 2020 at an aggregate price of $50 million.

Square has been involved with the currency for years and its Cash App, a payments service has allowed users to trade it since 2018. The app had three million active bitcoin customers in 2020, with a million new users buying the currency for the first time in January, the company said.

Twitter

Over at Dorsey's "other company" -- Twitter -- the social media giant has recently considered paying employees in cryptocurrencies if they prefer that form of payment.

"We've done a lot of the upfront thinking to consider how we might pay employees should they ask to be paid in bitcoin, how we might pay a vendor if they ask to be [paid] in bitcoin and whether we need to have bitcoin on our balance sheet should that happen," Twitter Chief Financial Officer Ned Segal told CNBC's "Squawk Box".

Tesla

Electric automaker Tesla announced in an SEC filing earlier this month that it has invested $1.5 billion in bitcoin to "further diversify and maximize" the return on its cash. Also, the company said that it expects to begin accepting bitcoin as a form of payment for its cars in the "near future."

"When fiat currency has negative real interest, only a fool wouldn’t look elsewhere," CEO Elon Musk explained in a tweet. "Bitcoin is almost as bs as fiat money. The keyword is "almost"."

Musk acknowledged that he was a "supporter of bitcoin" when asked about his thoughts on cryptocurrencies during a live-streamed interview on the popular audio chat app Club House on Feb.1.

"Many friends of mine have tried to convince me to get involved in bitcoin for a long time," he added.

MicroStrategy

Musk’s decision to add bitcoin to Tesla’s balance sheet followed an exchange he had with MicroStrategy CEO Michael Saylor. In December his mobile software/ business intelligence company said it had accumulated more than $1.3 billion worth of the cryptocurrency.
