Even after a recent 15% drop, Bitcoin still makes up about 68% of the cryptocurrency market. This means that currently, Bitcoin’s market cap is greater than all other altcoins combined: *Note: Figures have been rounded. This hasn’t always been the case for Bitcoin—in fact, its market share was a mere 32.8%, back in January 2018. However, within a year it had captured the majority of the market again. And ever since, it’s held a relatively stable piece of the pie.
Why does Bitcoin Have a Greater Market Value?
How has Bitcoin managed to remain top dog in the cryptocurrency market throughout the years? There are a few likely reasons:
It’s built a solid reputation Bitcoin was the first cryptocurrency on the scene, giving it a first-mover advantage. This is a fancy way of saying that the early bird gets the worm—or in Bitcoin’s case, media attention and investor trust. There’s a finite supply The world’s supply of Bitcoin maxes out at 21 million, and about 18.5 million are currently in circulation. This scarcity ideally increases its value over time. Other cryptocurrencies, like Ethereum’s coin Ether, are currently limitless. It’s more accessible than other cryptocurrencies Bitcoin has a much larger ecosystem than other cryptocurrencies. Because it has more applications and merchants that accept it, it’s more convenient than other digital coins.
Should We Even Compare Cryptocurrencies?
Not all crypto assets have the same intended use. For instance, the Ethereum network was created primarily to facilitate decentralized applications and smart contracts. So, while it’s interesting to compare Bitcoin’s market cap to other coins, it’s important to remember that they’re not necessarily direct competitors—and success for one doesn’t necessarily mean the death of others.

And all those sensors create reams of data, which will increase exponentially as the autonomous driving revolution gathers pace. With carmakers planning on uploading 50-70% of that data, this has serious implications for policymakers, manufacturers, and local network infrastructure. In this visualization from our sponsor Global X ETFs, we ask the question: will connected cars break the internet?
Data is a Plural Noun
Just how much data could it possibly be? There are lots of estimates out there, from as much as 450 TB per day for robotaxis, to as little as 0.383 TB per hour for a minimally connected car. This visualization adds up the outputs from sensors found in a typical connected car of the future, with at least some self-driving capabilities. The focus is on the kinds of sensors that an automated vehicle might use, because these are the data hogs. Sensors like the one that turns on your check-oil-light probably doesn’t produce that much data. But a 4K camera at 30 frames a second, on the other hand, produces 5.4 TB per hour. All together, you could have somewhere between 1.4 TB and 19 TB per hour. Given that U.S. drivers spend 17,600 minutes driving per year, a vehicle could produce between 380 and 5,100 TB every year. To put that upper range into perspective, the largest commercially available computer storage—the 100 TB SSD Exadrive from Nimbus—would be full in 5 hours. A standard Blu-ray disc (50 GB) would be full in under 2 seconds.
Lag is a Drag
The problem is twofold. In the first place, the internet is better at downloading than uploading. And this makes sense when you think about it. How often are you uploading a video, versus downloading or streaming one? Average global mobile download speeds were 30.78 MB/s in July 2022, against 8.55 MB/s for uploads. Fixed broadband is much higher of course, but no one is suggesting that you connect really, really long network cables to moving vehicles.
Ultimately, there isn’t enough bandwidth to go around. Consider the types of data traffic that a connected car could produce:
Vehicle-to-vehicle (V2V) Vehicle-to-grid (V2G) Vehicles-to-people (V2P) Vehicles-to-infrastructure (V2I) Vehicles-to-everything (V2E)
The network just won’t be able to handle it.
Moreover, lag needs to be relatively non-existent for roads to be safe. If a traffic camera detects that another car has run a red light and is about to t-bone you, that message needs to get to you right now, not in a few seconds.
Full to the Gunwales
The second problem is storage. Just where is all this data supposed to go? In 2021, total global data storage capacity was 8 zettabytes (ZB) and is set to double to 16 ZB by 2025.
One study predicted that connected cars could be producing up to 10 exabytes per month, a thousand-fold increase over current data volumes.
At that rate, 8 ZB will be full in 2.2 years, which seems like a long time until you consider that we still need a place to put the rest of our data too.
At the Bleeding Edge
Fortunately, not all of that data needs to be uploaded. As already noted, automakers are only interested in uploading some of that. Also, privacy legislation in some jurisdictions may not allow highly personal data, like a car’s exact location, to be shared with manufacturers.
Uploading could also move to off-peak hours to even out demand on network infrastructure. Plug in your EV at the end of the day to charge, and upload data in the evening, when network traffic is down. This would be good for maintenance logs, but less useful for the kind of real-time data discussed above.
For that, Edge Computing could hold the answer. The Automotive Edge Computing Consortium has a plan for a next generation network based on distributed computing on localized networks. Storage and computing resources stay closer to the data source—the connected car—to improve response times and reduce bandwidth loads.
Invest in the Future of Road Transport
By 2030, 95% of new vehicles sold will be connected vehicles, up from 50% today, and companies are racing to meet the challenge, creating investing opportunities.
