Elon Musk has reportedly lost $20 billion since his May 8 appearance on Saturday Night Live, as the news of Tesla halting Bitcoin payments for cars continues to send shockwaves across markets.

On May 7, the day before Musk made his appearance on SNL, Tesla stock was sitting at $669. In the week since, the stock has declined 14% to sit around $573. According to Forbes estimates, this sudden drop has seen Musk’s $166-billion net worth plunge by $20 billion down to around $145.5 billion.

The 14% drop this week adds to an overall downward trend for Tesla stock over the past 30 days. On April 14, TSLA shares were sitting at $784. Friday’s price of $573 marks a 26.91% decrease over this period, according to data from TradingView.

Musk’s escapades aren’t just causing volatility in Tesla stock prices of course, with Bitcoin’s (BTC) price declining 8.1% from $54,448 when he dropped his BTC payments bombshell on Thursday down to around $50,000 currently, according to CoinGecko.

Alex Mashinsky, CEO of digital asset lender Celcius Network, said the crypto industry didn’t need friends like Musk, telling Yahoo Finance that:

“Bitcoin is up 20,000,000% in the last decade — the best performing asset class over the last decade [...] — and the industry is going to do just fine without Elon.”

He noted that Tesla made a $300-million profit from selling a portion of its Bitcoin, which dramatically improved its Q1 bottom line. “So, obviously, they use Bitcoin to deliver a very important quarter for them,” he said. “So, you can’t have it both ways. You can’t say Bitcoin’s not good for me. So, Bitcoin doesn’t need Tesla.”

Michael Saylor comes out firing

MicroStrategy CEO Michael Saylor also came out firing, taking on Musk on Twitter about the billionaire’s claims Bitcoin is not environmentally friendly.

Musk posted links to articles that referenced “dirty coal” Bitcoin mining operations, such as the plant in Xinjiang that temporarily shut down for safety checks last month, which resulted in a sharp drop in the hash rate of China’s top mining pools. The links also point to the controversial expansion of Greenbridge’s gas-fired Bitcoin plant in New York.

Saylor fired back by arguing the cost of Bitcoin was worth it for the benefits:

“Bitcoin offers 8 billion people a superior technology to guarantee their human rights to property, as well as a solution to the global problem of inflation & currency devaluation which creates $10+ trillion in economic damage per year. Isn’t the fossil fuel mix second order?”

Saylor might be more upset than most as he was reportedly instrumental in convincing Musk to add $1.5 billion of BTC to Tesla’s balance sheet in the first place.

MicroStrategy took advantage of the dip caused by Musk’s announcement on Thursday by spending another $15 million to buy 271 BTC, taking its total haul to 91,850 BTC.

Hope for the future?

Not everyone saw Musk’s actions in a negative light. Anthony Scaramucci, CEO of investment firm SkyBridge Capital, suggested that this was part of Musk’s plan to help clean up Bitcoin mining by encouraging it to move to 100% renewables.

“Elon’s goal: level set the Bitcoin community and focus policymakers on the urgency for clean energy mining. The path to $1 million BTC and hyper-bitcoinization demands renewable mining. Elon will contribute mightily in this regard. He’s HODLing.”

He wagered 500,000 Satoshis that Musk would enter the “super clean” Bitcoin mining market.
