Bitcoin plummeted nearly 15% in Asian trading on May 13, 2021, after Tesla CEO Elon Musk announced the electric vehicle giant would suspend accepting bitcoin as payment for vehicles. The sharp selloff briefly dragged the flagship cryptocurrency down to $46,045.10 before a partial recovery trimmed losses to around 7.78%, bringing bitcoin back above the $50,000 mark.
The market turbulence followed Musk’s tweet stating Tesla was halting bitcoin transactions due to environmental concerns over the fossil fuel consumption linked to crypto mining. While Tesla confirmed it would not sell any of its existing bitcoin holdings, the reversal stunned investors and triggered a wave of profit-taking and panic selling across digital asset markets.

Environmental Concerns Shake Crypto Markets
Musk cited the rapidly increasing use of fossil fuels in bitcoin mining and transactions as the primary reason for the policy shift. His statement added that Tesla may resume accepting cryptocurrencies in the future—once mining transitions to more sustainable energy sources. He also left the door open for adopting alternative cryptocurrencies with lower energy footprints.
This sudden pivot raised questions about the long-term viability of energy-intensive blockchains amid growing scrutiny over climate impact. According to data from Cambridge University and the International Energy Agency, bitcoin mining consumes approximately as much electricity annually as the entire country of the Netherlands did in 2019. A recent Citigroup report noted that bitcoin’s energy usage has surged 66 times since late 2015, drawing increased regulatory and public attention.
Despite this, some industry experts argue that crypto mining can drive innovation in renewable energy adoption. ARK Invest, led by renowned investor Cathie Wood, released a report suggesting that mining operations could accelerate investments in solar power and support grid stability by utilizing excess renewable capacity. Jack Dorsey, co-founder of Twitter and Square, echoed these sentiments, tweeting that bitcoin “supports renewable energy.” Musk briefly responded with a single word: “Yes.”
Yet, his subsequent decision to pause bitcoin payments at Tesla has created confusion among supporters and analysts alike.
Ripple Effects Across the Crypto Ecosystem
The fallout extended beyond bitcoin. Ether, the second-largest cryptocurrency by market capitalization, briefly dropped 14% to $3,550 before recovering above $4,000. Other major digital assets also saw heightened volatility, reflecting broader market sensitivity to high-profile endorsements—or reversals—by influential figures.
Nic Carter, partner at Castle Island Ventures, expressed surprise at the abrupt change in stance: “He must have done due diligence before endorsing bitcoin for car purchases. Reversing course so quickly is unusual and hard to interpret.”
Tesla’s initial announcement in February 2021—that it had invested $1.5 billion in bitcoin and would begin accepting it as payment—was widely seen as a watershed moment for mainstream crypto adoption. Coming from a S&P 500 company with massive public visibility, the move lent credibility to digital currencies as both an investment and a viable payment method.
That decision triggered a powerful rally: bitcoin surged 16% the same day, marking its largest single-day gain since March 2020 when global financial markets were reeling from the onset of the pandemic.

Institutional Adoption: Momentum Before the Dip
Following Tesla’s lead, other financial giants began integrating crypto-friendly services. Mastercard announced plans to enable transactions using select cryptocurrencies on its network, while Bank of New York Mellon revealed it would offer custody and trading services for digital assets. These developments fueled optimism that traditional finance was embracing blockchain technology.
Bitcoin’s price trajectory reflected this growing confidence. From around $29,000 at the end of 2020, it climbed steadily through early 2021, peaking near $65,000 in April—just weeks before Musk’s latest announcement reversed the momentum.
Still, analysts note that price corrections are inherent to mature markets. The ability of bitcoin to rebound from double-digit drawdowns underscores increasing resilience within the ecosystem.
