The Bitcoin (BTC) price again reached an all-time high in 2025, as values exceeded over 123,352.5 USD on October 9, 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.

In March 2024 Bitcoin BTC reached a new all-time high with prices exceeding 73000 USD marking a milestone for the cryptocurrency market This surge was due to the approval of Bitcoin exchange-traded funds ETFs in the United States allowing investors to access Bitcoin without directly holding it This development increased Bitcoin’s credibility and brought fresh demand from institutional investors echoing previous price surges in 2021 when Tesla announced its 15 billion investment in Bitcoin and Coinbase was listed on the Nasdaq By the end of 2022 Bitcoin prices dropped sharply to 15000 USD following the collapse of cryptocurrency exchange FTX and its bankruptcy which caused a loss of confidence in the market By August 2024 Bitcoin rebounded to approximately 64178 USD but remained volatile due to inflation and interest rate hikes Unlike fiat currency like the US dollar Bitcoin’s supply is finite with 21 million coins as its maximum supply By September 2024 over 92 percent of Bitcoin had been mined Bitcoin’s value is tied to its scarcity and its mining process is regulated through halving events which cut the reward for mining every four years making it harder and more energy-intensive to mine The next halving event in 2024 will reduce the reward to 3125 BTC from its current 625 BTC The final Bitcoin is expected to be mined around 2140 The energy required to mine Bitcoin has led to criticisms about its environmental impact with estimates in 2021 suggesting that one Bitcoin transaction used as much energy as Argentina Bitcoin’s future price is difficult to predict due to the influence of large holders known as whales who own about 92 percent of all Bitcoin These whales can cause dramatic market swings by making large trades and many retail investors still dominate the market While institutional interest has grown it remains a small fraction compared to retail Bitcoin is vulnerable to external factors like regulatory changes and economic crises leading some to believe it is in a speculative bubble However others argue that Bitcoin is still in its early stages of adoption and will grow further as more institutions and governments recognize its potential as a hedge against inflation and a store of value 2024 has also seen the rise of Bitcoin Layer 2 technologies like the Lightning Network which improve scalability by enabling faster and cheaper transactions These innovations are crucial for Bitcoin’s wider adoption especially for day-to-day use and cross-border remittances At the same time central bank digital currencies CBDCs are gaining traction as several governments including China and the European Union have accelerated the development of their own state-controlled digital currencies while Bitcoin remains decentralized offering financial sovereignty for those who prefer independence from government control The rise of CBDCs is expected to increase interest in Bitcoin as a hedge against these centralized currencies Bitcoin’s journey in 2024 highlights its growing institutional acceptance alongside its inherent market volatility While the approval of Bitcoin ETFs has significantly boosted interest the market remains sensitive to events like exchange collapses and regulatory decisions With the limited supply of Bitcoin and improvements in its transaction efficiency it is expected to remain a key player in the financial world for years to come Whether Bitcoin is currently in a speculative bubble or on a sustainable path to greater adoption will ultimately be revealed over time.

Any form of currency that only exists digitally relying on cryptography to prevent counterfeiting and fraudulent transactions is defined as cryptocurrency. Bitcoin was the very first Cryptocurrency. It was invented in 2009 by an anonymous person, or group of people, who referred to themselves as Satoshi Nakamoto. When someone sends a bitcoin (or a fraction of a bitcoin) to someone else, “miners” record that transaction in a block and add the transaction to a digital ledger. These blocks are collectively known as the blockchain – an openly accessible ledger of every transaction ever made in bitcoin. Blockchains are distributed across many computers so that the record of transactions cannot be altered. Only 21 million bitcoins can ever be mined and about 17 million have been mined so far. Bitcoin is mined, or created, by people (miners) getting their computers to solve mathematical problems, in order to update and verify the ledger.

The value of bitcoin is determined by what people are willing to pay for it, and is very volatile, fluctuating wildly from day to day. In April 2013, the value of 1 bitcoin (BTC) was around $100 USD. At the beginning of 2017 its value was $1,022 USD and by the 15th of December it was worth $19,497. As of the 3rd of March 2018, 1 BTC sells for $11,513 USD. So, the time series analysis of bitcoin series is very challenging.

Bitcoin dominance steadily declined in April 2024 to below 50 percent, amid rumors of central banks halting or potentially lowering interest rates in the future. 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". Why dominance matters is because market caps of any crypto can change relatively quickly, either due to sudden price changes or a change of recorded trading volume. Essentially, the figure somewhat resembles a trading sentiment, revealing whether Bitcoin investors are responding to certain events or whether Bitcoin is losing out on functions offered by, for example, stablecoins or NFT tokens. "Dominance" criticism: Ethereum and stablecoin The interpretation of the Bitcoin metric is not without its criticism. When first conceived, Bitcoin was the first cryptocurrency to be created and had a substantial market share within all cryptocurrencies? The overall share of stablecoins, such as Tether, as well as Ethereum increasingly start to resemble that of Bitcoin, however. Some analysts argue against this comparison. For one, they point towards the large influence of trading activity between Bitcoin and Ethereum in the dominance metric. Second, they argue that stablecoins can be traded in for Bitcoin and Ethereum, essentially showing how much investors are willing to engage with "regular" cryptocurrency. A rally around Bitcoin in late 2023? By December 2023, the Bitcoin price reached roughly 41,000 U.S. dollars — the first time in 20 months such a value was reached. A weaker U.S. dollar, speculation on decreasing interest rates, and a potential Bitcoin ETF approval are believed to be at the heart of this price increase. Whether this will hold in 2024 is unclear: The monthly interest rate from the U.S. Fed is speculated to decrease in 2024, despite a vow of "higher for longer". In December 2023, the thought of decreasing interest rates and the potential of a Bitcoin ETF fuelled market sentiment towards riskier assets.

Bitcoin's circulating supply has grown steadily since its inception in 2009, reaching over ***** million coins by early October 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 October 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 discussing 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.

Bitcoin transaction fluctuated significantly as more users started to display interest in the cryptocurrency in late 2020 and early 2021. By 2025, this fee was worth over *** U.S. dollar, but it came down in August 2025 to **** U.S. dollars. Transaction fees refer to the money paid to Bitcoin's miners to get transactions accepted and costs increases can occur when user numbers increase: As the blockchain has limited space available to process all the transactions, it effectively becomes congested. Growing transaction fees therefore represent both the number of Bitcoin transactions that are waiting in line to be processed, but are also meant as an incentive to miners to process the especially large transactions - as they are more profitable for them. The number of Bitcoins processed on a single day reached its highest value at the beginning of 2021.

Tesla made headlines in 2021 when it comes to buying Bitcoin (BTC), but the software company MicroStrategy held ********** their amount of the cryptocurrency. This according to an overview created by accessing what information was available from publicly listed companies, such as from their quarterly reports or filings. The figures provided are on how much Bitcoin the companies have bought and keep in their corporate treasury, essentially making cryptocurrencies part of their assets and that company's investment strategy. Two companies stand out in this list: first, Tesla announced in March 2021 it would accept BTC directly - Bitcoins paid for their cars would be retained as Bitcoin, and not converted from BTC to U.S. dollar. This is unlike other companies that accept Bitcoin as a payment method, like Microsoft, which uses a payment processor called BitPay to convert cryptocurrency to fiat currency. Second, there is Coinbase: One of the world's largest cryptocurrency exchanges amid a Bitcoin price surge, the U.S. company went public in April 2021 and was considered a potential blockbuster IPO.

The Root Mean Square (RMS) difference between the modeled curve and original time-series never exceeds a ~26%. Average length of subdataset is approx. 190 days (median ~ 180).

As of July 2021, the difference in Bitcoin prices between South Korean cryptocurrency exchange Upbit and the world's largest crypto exchange Binance was around 0.12 percent, down from around 20.8 percent on May 19. Also known as the "kimchi premium," the difference in Bitcoin prices between South Korean and foreign crypto exchanges rose to an all-time high of more than 20 percent in April and May, meaning that Bitcoin prices on South Korean exchanges were much more expensive than on other foreign exchanges.

The transaction fee of a transaction involving Bitcoin slowly increased during April 2024, as trading volume grew right before the Bitcoin halving. The fee of ** USD, however, was still in stark contrast to the first wave of public interest in the cryptocurrency, when the fee per transaction was over ** U.S. dollars. Regardless, the Bitcoin trading volume in the United States was bigger in 2017 than it was during 2020.

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 0.26 U.S. dollars on October 9, 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.

Crypto 24h trading volume declined as 2023 progressed, with figures being one-third lower than in 2022. The decline follows Binance - one of the biggest crypto exchanges in the world - received lawsuits in the United States. Observations are also that the crypto market was quiet after April, citing a lack of a "strong overarching narrative". This contrasts with 2021 and 2022 when cryptocurrency dominated the news and many people sought fortune in the digital currency. Bitcoin developments Bitcoin's trade volume slowed in the second quarter of 2023, after hitting a noticeable growth at the beginning of the year. The coin outperformed most of the market. Some attribute this to the announcement in June 2023 that BlackRock filed for a Bitcoin ETF. This iShares Bitcoin Trust was to use Coinbase Custody as its custodian. Regulators in the United States had not yet approved any applications for spot ETFs on Bitcoin. Changes in Ethereum staking in 2023 Ethereum's trade volume changed in 2023 due to the rollout of the Shapella (Shanghai and Cappella) upgrade. The update allowed investors to withdraw (unstake) Ethereum deposited into the network. Staking can be somewhat compared to depositing money at a bank, where one would submit money to be held and gains interest as time goes by. Lido has the highest staking pool (a platform that allows for staking) in Ethereum, higher than major crypto exchanges Coinbase and Kraken. As of October 1, 2025, the 24h trading volume stands at 168.25.

The Litecoin cryptocurrency peaked in both 2017 and 2020, reaching prices worth around 250 dollars, but did not reach this by 2022. As of October 9, 2025, one Litecoin token was worth 118.58 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 LitecoinCryptocurrencies 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.

Ethereum market sentiment was bullish in April and May 2021, as is shown in the development of the cryptocurrency's NVT ratio. The Network Value to Transactions or NVT ratio is somewhat comparable to a P/E ratio, in that it compares the number of transactions of a particular coin on a set day against that coin's market cap. A low NVT ratio means that that transaction volume of a cryptocurrency is growing faster than the coin's market cap - meaning investor sentiment is bullish, or optimistic - whereas a high ratio refers to a network that has a relatively high network value but low network activity - meaning sentiment is bearish, or negative.

The number of addresses that actively sent or received Ethereum coins on the blockchain peaked in April 2021, nearly reaching one million on a single day. In the following months, this number varied dramatically from day to day, reaching below 500,000 addresses at is lowest point. Although the cryptocurrency has an unlimited supply - unlike Bitcoin, of which there can only be 21 million tokens and not a single more - the Ethereum blockchain received an update in August 2021, EIP-1559, that both increased the block size needed to create new coins and destroyed any transactions fees, rather then send them to the original miners. This led to a decline in issuance, as mining Ethereum essentially was made less profitable. This is expected to decline further when Ethereum 2.0 arrives.

The market cap of Ripple, or XRP, grew substantially in November 2024, after the results of the United States elections. At the beginning of 2024, the cryptocurrency had a market capitalization of around ** billion U.S. dollars. One year later, this had changed to *** billion U.S. dollars. The company Ripple faced charges in 2020 from the U.S. Securities and Exchange Commission (SEC), which led to a *** million U.S. dollar fine in August 2024 as the company was sentenced for violating investor-protection laws. The SEC appealed this decision, deeming the sentence too low. The results of the U.S. elections in November 2024, however, and the announced changes to the leadership of the SEC, made crypto investors believe that the case against Ripple Labs might be dropped in January 2025.

In April 2021, the Ethereum market cap reached new heights and grew to over *** billion U.S. dollars - the first time this cryptocurrency achieved that feat. The market capitalization in August 2020 was half this amount. Market capitalization is calculated by multiplying the total number of Ethereum in circulation by the Ethereum price. Compared to the Bitcoin market capitalization, however, Ethereum was not yet as popular.
