Tesla’s Bitcoin investment has been a rollercoaster ride of gains and losses
One of the ultimate joyrides as a human is riding a rollercoaster. The anticipation of sitting in the train, waiting for dispatch as you slowly climb up the first gigantic hill, all for the anticipation to break. Suddenly, you’re falling down a 200+ foot drop, awaiting the next rise, which will unequivocally result in another slight drop. A short time later, you’re right back to where you started, in a pavilion, waiting to get off of the ride.
Tesla’s Bitcoin investment has been a comparable scenario described above: a meteoric climb, succeeded by a sharp drop, followed by tiny peaks and valleys. Ultimately, Tesla is right back to where it started.
In the company’s 10-Q filing with the SEC earlier today, the electric car company based out of Northern California detailed its tumultuous experience with Bitcoin, the cryptocurrency that could likely be attributed to most of the ranting and raving regarding digital assets. It allowed anyone who can access the document a peek into what kind of swings Tesla has been experiencing through its investment into Bitcoin, which was detailed in the 10-K filing after Q4 2020 results.
Climbing up the first hill
Tesla’s $1.5 billion investment started in the gate and quickly took off up the first hill of gains like a launch rollercoaster. The first hill lasted quite some time, as Bitcoin eclipsed $64,000 and put Tesla up a substantial sum. It is not known how many BTC Tesla received when it initially invested the $1.5 billion, but it is estimated that the price of the crypto was between $29,333 and $37,020. This would put Tesla’s potential holdings at between 37,020 to 51,137 BTC.
It was estimated that Tesla made close to or more than $1 billion as Bitcoin continued to rise in value through the early portion of 2021. According to an April report from Teslarati, “Even if Tesla only acquired the minimal amount of 37,020 Bitcoin in January, the company’s $1.5 billion investment would still be worth $2.3 billion today, hinting at a healthy profit of $800 million,” and that’s figure originates from the possibility of their lowest BTC investment. Tesla said it realized gains of $128 million from its digital assets in March 2021 alone.
After reaching all-time highs of over $64,829, Bitcoin started to tumble, bringing Tesla’s rollercoaster ride down its first and largest hill.
The Big Drop
The big drop occurred as Bitcoin began to slide in mid-May. From May 8th to the 22nd, Bitcoin slid from $58,788 to under $37,500. At one point, BTC even struck the $30,000 range before recovering to $38,000.
The slide was met with uncertainty, worry, and anxiety by many investors. But Musk solidified the fact that Tesla would keep its “diamond hands” and continue holding BTC, despite the volatility experienced during its epic fall.
The company wrote:
“During the three and six months ended June 30, 2021, we recorded $23 million and $50 million, respectively, of impairment losses on such digital assets.”
The Ride: Back to the Beginning
Through the tumultuous ride of the BTC rollercoaster through the first half of 2021, Tesla rode the hills, the turns, and loops and ended up right back where it started (basically). As of June 30, Tesla says the fair market value of such digital assets “was $1.47 billion.” Additionally, the company said that “as of June 30, 2021, the carrying value of our digital assets held was $1.31 billion, which reflects cumulative impairments of $50 million.”
It has been exciting, and it has been uncertain, but Tesla, like the rest of investors, is just along for the ride. Bitcoin’s volatility over the past few months may not have been expected by the diehard cryptocurrency supporters that have vocally supported it since its early days. Still, like anything else, it is an investment. Tesla is banking on a wider adoption of crypto in the coming months and years, something it has dabbled with in the past.

How to use Grok Bot to block spam calls and texts
Musk told users to ask Grok Bot to scrub their phone numbers from spam lists.
Elon Musk has a new use case for Grok Bot, and it is the spam call. On Thursday he replied to an X user named Arash with a short instruction: “Ask your @Grok @Bot to remove your phone number from spam call & text lists!” Arash had said he got tired of the calls, had an AI bot find his number on listing sites and file removal requests, and packaged the process as a free skill for others.
The skill is called Spam-Call Scrubber, which is described to find a phone number on people search sites and data brokers, submits the opt outs, completes the confirmation emails those sites send back, and rechecks on a schedule the user picks. Using it requires the Grok Bot app. The pitch is time saved, since most broker opt outs sit behind separate forms on separate sites.
Ask your @Grok @Bot to remove your phone number from spam call & text lists!

Musk said Grok Bot now gives each bot its own email address, and that it can detect scam emails. On Thursday he also said SpaceX would make users whole if the bot botches a purchase or leaks a card, then told users to shop away from Amazon after the retailer blocked the agent, as Teslarati reported. The terms of service we reviewed at the time put responsibility for what an agent does on the user.
For Tesla owners, Grok Bot is not just a phone app. Tesla brought Grok Bot into its vehicles on September 22, and we argued earlier this week that the Cybercab’s real advantage may be the errands it runs during a ride. Every Cybercab and the rest of the Model Y Robotaxi fleet has it enabled. The more routine tasks like this one become, the more a rider has reason to hand over something personal in the back seat.
The new Spam-Call Scrubber skill can be downloaded for free and works on sites that honor removal requests, while noting that listings can reappear, and illegal robocallers do not check any registry. Whether Spam-Call Scrubber cuts anyone’s call volume is something the first wave of users will find out, and Musk’s endorsement guarantees that wave is coming.
Investor's Corner
Tesla’s flying Roadster just revealed something bigger than the car
Analysts say the Roadster demo puts a Tesla and SpaceX merger back on the table.
The Roadster unveiling near Waco ended Thursday night, and by Friday morning much of the investor reaction had less to do with the car than with who owns the rocket technology inside it.
Wedbush analyst Dan Ives said the event “puts the Tesla/SpaceX relationship on the table in a tangible way,” pointing to the propulsion, pressure vessel and control hardware sitting on a Tesla product. Gene Munster of Deepwater Asset Management called the demo “a ridiculous display of engineering” with “no commercial value” beyond embarrassing traditional automakers, though he said it showed Musk wants the two companies together.
The more specific forecast came a day earlier from Barclays. Analyst Dan Levy told clients a deal could be announced before Tesla’s annual meeting, which must happen by December 6, and that an announcement in late October or early November could make shareholder approval harder. Barclays expects SpaceX to be the buyer in an all stock deal, with Tesla holders receiving SpaceX shares at a premium, based on market values of roughly $2.1 trillion for SpaceX and $1.5 trillion for Tesla. If nothing lands around the meeting, the bank still sees an announcement within 6 to 12 months.
The Roadster demo just added more weight to merger speculations. Tesla’s demo used cold gas thrusters and pressure tanks of the kind SpaceX uses on Falcon 9, and Musk described the car as a collaboration between Tesla and SpaceX engineers, as we mentioned in our breakdown of the three Roadster configurations.
Musk has not publicly addressed a deal since the event, as far as we have seen. His most direct answer remains the one he gave at the All In Summit, when he said that with so much collaboration, “who can imagine what action one might take” without ruling anything out. Ives has held to a 2027 timeline since his March note, and Musk pushed back on the China piece of the speculation when ARK floated a year end announcement in August.
The next test is Tesla’s third quarter earnings call on October 21. However, we recall in July that Musk told analysts, “we can’t talk about combining companies and that kind of thing on an earnings call,” so a clear answer wouldn’t be expected.

How Tesla’s Roadster fan system and thrusters are built to dominate the corners
Tesla’s Roadster uses fans, active wings and cold gas thrusters to create grip at any speed.
Tesla’s new Roadster is best known for flipping through the air in Texas, but the technology that matters most for a race track is the stuff that keeps it on the ground. Tesla’s Roadster page describes a multi-mode fan and ground sealing system that acts as a downforce generator, pulling air out from beneath the car. Tesla says it provides enough suction to hold the vehicle upside down, even when stationary.
That is the key difference from the wings and diffusers on a normal supercar. Conventional aero only makes downforce when the car is moving, and it grows with speed, so a car has the least grip in the slow corners and under hard braking. A fan system makes downforce at any speed. Tesla’s patent, which we covered last year, describes fans and deployable skirts that create sealed or partially sealed regions under the car, with the fans extracting air to lower the pressure and increase grip and stability.
Still processing this … the most unreal thing I’ve seen. https://t.co/HtEuvnkZjY

Tesla pairs that with active wings, a next generation steer by wire system and a Track Mode that lowers the car and changes the suspension, with high downforce and low drag settings for the circuit. To keep weight down, Tesla points to magnesium, titanium and carbon fiber, manual controls and a fixed seat position, which it says lets the car respond to driver inputs almost instantly.
Tesla Roadster: Three configs, one can fly, 0-60 in 0.8 seconds
The cold gas thrusters are the other half. On the Thrust version they sit at the rear and Tesla says they take the car from 0 to 60 mph in under 0.9 seconds, while the Rocket version adds perimeter thrusters for forward, upward and lateral rotational movement. Tesla says the all electric actuators make micro adjustments within a fraction of a second.

Musk has been talking about records for years. In June 2019 he said, “We’re going to do things with the new Roadster that are kind of unfair to other cars.” That September, when a follower asked whether the Roadster would beat the Nürburgring production car record, he replied with one word, “Absolutely,” as we reported at the time. In February 2024 he said Tesla had “radically increased the design goals” for the car and that its sub one second 0 to 60 time would be “the least interesting part.”
There are caveats. Tesla has not published a lap time or a verified cornering figure, so the record talk is still a promise rather than a result. Tesla also says the car is not approved for public road use, and the thruster features are limited to the Rocket trim, which is invite only. Fan cars have also been banned or withdrawn before, and getting a sealed underbody to work on a rough public road is a harder problem than on a smooth track. The first real test will be an official lap at a circuit.
