Bitcoin's Recent Price Movements

Bitcoin's price has recently declined to a near low of $60,000 (£44,500), bringing renewed attention to the dynamic world of cryptocurrencies.

As the most valuable digital currency globally, Bitcoin frequently makes headlines when it reaches record highs or experiences significant drops in value. In 2026, its price has dipped to levels not seen since before US President Donald Trump assumed office.

The volatility of the crypto market is often accompanied by complex terminology such as ETFs, blockchains, and stablecoins, which can make understanding the market challenging for many.

If you are encountering these terms for the first time or need a refresher, the following sections explain key cryptocurrency concepts.

What is Bitcoin?

Bitcoin is a cryptocurrency, meaning it is a type of digital currency. Unlike traditional currencies, Bitcoin operates without control from centralized financial institutions.

This decentralization appeals to those who believe it can provide financial freedom. However, it also contributes to Bitcoin's extreme volatility, with its value fluctuating based on the buying and selling activities of users.

Donald Trump has pledged to make the US the "crypto capital of the world," reversing his earlier statement that Bitcoin was a "scam."

"The US will become the leading hub for cryptocurrency innovation and adoption," Trump stated in a recent announcement.

Bitcoin's price surpassed the significant milestone of $100,000 in December 2024, then increased to $120,000 by July 2025 as US lawmakers prepared to debate legislation regulating digital assets.

In October 2025, Bitcoin reached an all-time high of approximately $126,000, driven by sustained institutional investment and positive market sentiment. However, its value has been known to decline as rapidly as it rises.

In early February 2026, the price fell below $65,000, effectively erasing gains made during President Trump's tenure.

A similar decline occurred recently, with Bitcoin dropping below $62,000 on June 5, 2026, raising concerns that it could lose more than half of its peak value.

Amid these frequent price fluctuations, speculation continues about the true identity of Bitcoin's enigmatic creator, known only as Satoshi Nakamoto.

Blockchain Technology

Blockchain is the foundational technology behind all cryptocurrencies and related products such as non-fungible tokens (NFTs). Essentially, it is a virtual ledger that records every cryptocurrency transaction.

Transactions are grouped into blocks that are linked sequentially, forming a chain—hence the term "blockchain."

A vast network of volunteers verifies each transaction's authenticity using computer programs. The first individual to validate transactions on Bitcoin's network receives a reward in Bitcoin, a process known as mining.

Mining is potentially lucrative but controversial due to the substantial energy consumption involved, as participants worldwide compete to be the first to update the blockchain.

Bitcoin 'Halving'

The blockchain operates by rewarding "miners" who validate transactions with cryptocurrency payments.

Unlike some digital currencies, Bitcoin has a capped supply of 21 million coins, most of which are already in circulation.

Approximately every four years, or when the Bitcoin blockchain reaches a specific size, the reward for miners is halved. The most recent "halving" occurred on April 20, 2024, reducing the reward from 6.25 bitcoins to 3.125.

This mechanism extends Bitcoin's supply over time and theoretically increases demand. However, reduced rewards may lead some miners to question the financial viability of maintaining their energy-intensive operations.

Crypto Exchanges

A crypto exchange is a digital platform where investors can buy, sell, and trade cryptocurrencies.

Functioning similarly to traditional brokerages, crypto exchanges allow users to convert traditional currencies such as pounds or dollars into cryptocurrencies like Bitcoin or Ethereum. Most transactions incur fees.

Crypto Wallets

Crypto wallets are storage solutions where investors keep their cryptocurrencies. There are two main types: hot wallets and cold wallets.

Hot wallets are connected to the internet, providing easy access and facilitating quick transfers.

Cold wallets are physical devices, such as specially designed USB sticks, that store cryptocurrencies offline, offering enhanced security for long-term storage.

Ethereum

Ethereum refers both to the second-largest cryptocurrency after Bitcoin, represented by the Ether token, and the blockchain technology that supports it.

Ethereum enables a variety of applications and digital assets, including non-fungible tokens.

It operates similarly to Bitcoin but transitioned in 2022 to a more energy-efficient system requiring fewer computers and less energy.

Exchange-Traded Funds (ETFs)

ETFs are investment portfolios that allow investors to speculate on multiple assets without purchasing them individually. Traded on stock exchanges like shares, their value fluctuates based on the portfolio's real-time performance.

Portfolios may include combinations of assets such as gold and silver bullion or shares from various sectors like technology and insurance.

A spot Bitcoin ETF purchases the cryptocurrency directly at its current price throughout the trading day.

While some ETFs previously held Bitcoin indirectly, the US approved several spot Bitcoin ETFs in January 2024. This enabled new investors, including investment management firms like BlackRock and Fidelity, to enter the Bitcoin market without managing digital wallets or navigating crypto exchanges.

Meme Coins

Meme coins are cryptocurrencies created primarily for entertainment and speculative purposes.

They often capitalize on social media trends or viral memes, such as the internet-famous pygmy hippo Moo Deng.

However, meme coins face criticism for their speculative nature and the high risk they pose to investors, as they frequently lack long-term value accumulation potential.

They are also vulnerable to "rug pulls," where promoters artificially inflate the coin's price by attracting buyers, then cease trading and abscond with the proceeds.

Some celebrities have faced backlash after launching meme coins.

Stablecoins

Stablecoins are cryptocurrencies designed to maintain a stable value, contrasting with the volatility typical of other digital currencies.

This stability is usually achieved by pegging the coin's price to an existing asset, such as the US dollar or pound sterling, making them theoretically less volatile.

Stablecoins are typically managed by companies that issue them, with transactions recorded on digital ledgers.

While some view stablecoins as the future of finance, notable price collapses have raised regulatory concerns about their risks and questioned their claimed stability.

XRP and Ripple

XRP is a cryptocurrency used by the XRP Ledger platform. Created in 2012 by the co-founders of Ripple Labs, it was designed as a faster, cheaper alternative to Bitcoin.

XRP has a fixed supply of 100 billion coins, all created at launch. Ripple holds a significant portion and releases coins into circulation periodically.

Unlike Bitcoin, XRP transactions are verified through consensus, requiring agreement from the majority of validators on its peer-to-peer network before inclusion in the blockchain.

This consensus mechanism allows many transactions to occur simultaneously, with high speed and low cost, making XRP attractive to financial institutions and for cross-border payments.

However, XRP has also faced regulatory scrutiny and experienced sudden, sharp declines in value.
