The Bitcoin (BTC) price again reached an all-time high in 2025, as values exceeded over 117,901.63 USD on July 20, 2025. Price hikes in early 2025 were connected to the approval of Bitcoin ETFs in the United States, while previous hikes in 2021 were due to events involving Tesla and Coinbase, respectively. Tesla's announcement in March 2021 that it had acquired 1.5 billion U.S. dollars' worth of the digital coin, for example, as well as the IPO of the U.S.'s biggest crypto exchange, fueled mass interest. The market was noticeably different by the end of 2022, however, after another crypto exchange, FTX, filed for bankruptcy.Is the world running out of Bitcoin?Unlike fiat currency like the U.S. dollar - as the Federal Reserve can simply decide to print more banknotes - Bitcoin's supply is finite: BTC has a maximum supply embedded in its design, of which roughly 89 percent had been reached in April 2021. It is believed that Bitcoin will run out by 2040, despite more powerful mining equipment. This is because mining becomes exponentially more difficult and power-hungry every four years, a part of Bitcoin's original design. Because of this, a Bitcoin mining transaction could equal the energy consumption of a small country in 2021.Bitcoin's price outlook: a potential bubble?Cryptocurrencies have few metrics available that allow for forecasting, if only because it is rumored that only a few cryptocurrency holders own a large portion of the available supply. These large holders - referred to as 'whales'-are' said to make up two percent of anonymous ownership accounts, while owning roughly 92 percent of BTC. On top of this, most people who use cryptocurrency-related services worldwide are retail clients rather than institutional investors. This means outlooks on whether Bitcoin prices will fall or grow are difficult to measure, as movements from one large whale are already having a significant impact on this market.

By 2025, the Bitcoin market cap had grown to over ***** billion USD as the cryptocurrency kept growing. Market capitalization is calculated by multiplying the total number of Bitcoins in circulation by the Bitcoin price. The Bitcoin market capitalization increased from approximately *** billion U.S. dollars in 2013 to several times this amount since its surge in popularity. Dominance The Bitcoin market cap takes up a significant portion of the overall cryptocurrency market cap. This is referred to as "dominance". Within the crypto world, this so-called "dominance" ratio is one of the oldest and most investigated metrics available. It measures the coin's market cap relative to the overall crypto market — effectively showing how strong Bitcoin compared to all the other cryptocurrencies that are not BTC, called "altcoins". The Bitcoin dominance was above ** percent. Maximum supply and scarcity Bitcoin is unusual from other cryptocurrencies in that its maximum supply is getting closer. By 2025, well over ** million out of all 21 million possible Bitcoin had been created. Bitcoin's supply is expected to reach its maximum around the year 2140, likely making mining more energy-intensive.

Ethereum's price history suggests that that crypto was worth significantly less in 2022 than during late 2021, although nowhere near the lowest price recorded. Much like Bitcoin (BTC), the price of ETH went up in 2021 but for different reasons altogether: Ethereum, for instance, hit the news when a digital art piece was sold as the world’s most expensive NFT for over 38,000 ETH - or 69.3 million U.S. dollars. Unlike Bitcoin - of which the price growth was fueled by the IPO of the U.S.’ biggest crypto trader Coinbase - the rally on Ethereum came from technological developments that caused much excitement among traders. First, the so-called “Berlin update” rolled out on the Ethereum network in April 2021, an update which would eventually lead to the Ethereum Merge in 2022 and reduced ETH gas prices - or reduced transaction fees. The collapse of FTX in late 2022, however, changed much for the cryptocurrency. As of May 4, 2025, Ethereum was worth 1,808.59 U.S. dollars - significantly less than the 4,400 U.S. dollars by the end of 2021. Ethereum’s future and the DeFi industry Price developments on Ethereum are difficult to predict, but cannot be seen without the world of DeFi - or Decentralized Finance. This industry used technology to remove intermediaries between parties in a financial transaction. One example includes crypto wallets such as Coinbase Wallet that grew in popularity recently, with other examples including smart contractor Uniswap, Maker (responsible for stablecoin DAI), moneylender Dharma and market protocol Compound. Ethereum’s future developments are tied with this industry: Unlike Bitcoin and Ripple, Ethereum is technically not a currency but an open-source software platform for blockchain applications - with Ether being the cryptocurrency that is used inside the Ethereum network. Essentially, Ethereum facilitates DeFi - meaning that if DeFi does well, so does Ethereum. NFTs: the most well-known application of Ethereum NFTs or non-fungible tokens grew nearly ten-fold between 2018 and 2020, as can be seen in the market cap of NFTs worldwide. These digital blockchain assets can essentially function as a unique code connected to a digital file, allowing to distinguish the original file from any potential copies. This application is especially prominent in crypto art, although there are other applications: gaming, sports and collectibles are other segments where NFT sales occur.

Bitcoin's circulating supply has grown steadily since its inception in 2009, reaching over ** million coins by early 2025. This gradual increase reflects the cryptocurrency's design, which put a limit of ** million on the total number of bitcoins that can ever exist. This impacts the Bitcoin price somewhat, as its scarcity can lead to volatility on the market. Maximum supply and scarcity Bitcoin is unusual from other cryptocurrencies in that its maximum supply is getting closer. By 2025, more than ** percent of all possible Bitcoin had been created. That said, Bitcoin's circulating supply is expected to reach its maximum around the year 2140. Meanwhile, mining becomes exponentially more difficult and energy-intensive. Institutional investors In 2025, countries like the United States openly started discussion the possibility of buying bitcoins to hold in reserve. By the time of writing, it was unclear whether this would happen. Nevertheless, institutional investors displayed more interest in the cryptocurrency than before. Certain companies owned several thousands of Bitcoin tokens in 2025, for example. This and the limited number of Bitcoin may further fuel price volatility.

The price of the cryptocurrency based on the famous internet meme broke its price decline in early November 2022, as people started buying the coin after FTX's collapse. This rally only lasted for a few days, however, as a Dogecoin was worth roughly 0.24 U.S. dollars on July 20, 2025. This is a different development than in 2021, when the crypto became very popular in a short amount of time. Between January 28 and January 29, 2021, Dogecoin's value grew by around 216 percent to 0.023535 U.S. dollars after comments from Tesla CEO Elon Musk. The digital coin quickly grew to become the most talked-about cryptocurrency available, not necessarily for its price - the prices of Bitcoin (BTC), Ethereum (ETH), Ripple (XRP), and several other virtual currencies were much higher than those of DOGE - but for its growth.

Bitcoin trading volume peaked in late February 2021 to a level much higher in the rest of the year, marking a significant month in the coin's history. Whilst there is no clear explanation why the trade volume went up so much on February 26, Bitcoin's price development suggests the cryptocurrency's value around that time declined somewhat after weeks of growth and continued media attention. That morning, Bitcoin went down by around ** percent - potentially sparking a buying frenzy for people who saw this as an opportune time to invest in the coin. Indeed, most consumers in both the U.S. and the UK invest in crypto for growth prospects. As of July 22, 2025, the Bitcoin trading volume was recorded at 46.34.

Bitcoin's annualized footprint in electricity consumption reached an all-time high in early 2022, then believed to be higher than the power consumption of Finland. This is according to a source that tries to estimate the energy consumption of Bitcoin (BTC). It does by assuming that miner's costs and income are the same thing: The higher the miner's income, the more powerful machinery it can support. As of May 19, 2025, Bitcoin's energy consumption fell in between the consumption of Australia or the Netherlands. Note, however, there is no central authority where cryptominers report their figures to. Exponential growth As Bitcoin has a maximum supply, the closer the cryptocurrency gets to its limit of 21 million coins, the more effort it takes to mine. Not every cryptocurrency has a maximum supply. Bitcoin, however, stands out as more than 90 percent of all its coins have already been created. This exponential growth cycle indirectly impacts the overall size of the blockchain as well, as it currently grows less fast than it did several years ago. Which countries mine Bitcoin the most? According to the latest available estimates, the United States had a higher Bitcoin mining hashrate than China. This research - using IP addresses from hashers accessing certain Bitcoin mining pools, a method the source admits can lead to issues - was last held in 2022, however. It is generally assumed that the different electricity prices worldwide may impact the decision on where to mine for Bitcoin.

The average energy consumption for one single Bitcoin transaction in 2025 could equal several hundreds of thousands of VISA card transactions. This according to a source that tries to estimate the energy consumption of both Bitcoin (BTC) over time. It does so by estimating how much income miners possibly spend on electricity, as there is no institution that tracks how much energy the cryptocurrency actually consumes. This also applies to which countries mine the most Bitcoin, as this is estimated by cross referencing IP addresses. A matter of design: why Bitcoin consumes so much energy Of all the 21 million Bitcoins that can exist at the same time, nearly 90 percent was already mined in mid-2021. This, however, does not necessarily mean that the Bitcoin supply is running out as the last Bitcoin was forecast to be mined around the year 2140. This is a design choice in the cryptocurrency: The closer Bitcoin gets to its supply limits, the computing power – and therefore energy - needed to mine goes up incrementally. The BTC mining difficulty or amount of computing power being applied to mine Bitcoin reflects that: Bitcoin mining in, say, 2014 – when there were less Bitcoin in circulation - was easier and less energy consuming than in 2021. By then, there were significantly more coins in circulation and the cryptocurrency’s design essentially tries to halt the creation of more. China’s doubts on whether Bitcoin is green Over the course of 2021, the price of Bitcoin was over 60,000 U.S. dollars but by the summer only half of that amount remained. This was partially caused by China’s Financial Stability and Development Committee trying to curb domestic crypto mining since May 2021 – which led some to doubt whether there was a future for the cryptocurrency. China’s efforts are said to have been triggered due to remote mining farms demanding so much electricity that idle coal mines were restarted without government approval. Whilst this was never confirmed, China is generally seen as the most coal consuming country in the world.

The Litecoin cryptocurrency peaked in both 2017 and 2020 - reaching prices worth around 250 dollars - but did not reach this by 2022. As of May 4, 2025, one Litecoin token was worth 85.02 U.S. dollars. Litecoin's price was relatively volatile recently, revealing high price swings between months. What is a cryptocurrency? Cryptocurrencies are digital currencies that do not have a centralized regulating authority. The first of these, Bitcoin, introduced a technology called blockchain, in which a distributed ledger records every transaction on every bitcoin in circulation to prevent fraud. Litecoin also uses this technology. To accommodate the demands of constant ledger updates, users sell computational power in exchange for an amount of Litecoin, a process known as mining. More about Litecoin Cryptocurrencies are still an emerging technology, and few are using them for transactions. As such, most users are speculators who look at the value of all coins in circulation as the market capitalization rather than money supply. Still, the average number of Litecoin transactions ranges in the tens of thousands, meaning that the cryptocurrency has a substantial financial footprint.
