Cryptocurrencies: Bitcoin, Stablecoin Dominating The Crypto Market

Cryptocurrencies are digital or virtual assets that use cryptography for security and operate on decentralized networks based on blockchain technology, enabling peer-to-peer transactions without the need for intermediaries like banks. They are designed to function as a medium of exchange, a store of value, or a unit of account.

Bitcoin, the first and most well-known cryptocurrency, was created in 2009 and is characterized by its limited supply, permissionlessness, portability and high price volatility, making it suitable as a store of value, an investment or hedge against inflation.

Stablecoin is a specific type of cryptocurrency designed to minimize price volatility by pegging its value to a stable external asset, such as a fiat currency (like the US dollar), a commodity (like gold), or a basket of assets.

This pegging mechanism allows stablecoins to maintain a relatively constant value, making them more practical for use in everyday transactions, remittances, and as a stable store of value within the volatile cryptocurrency ecosystem. They are often used as a bridge between traditional finance and digital assets, enabling faster and cheaper cross-border payments and serving unbanked populations.

The global market for stablecoins has seen significant growth, with a collective market capitalization exceeding $250 billion as of 2025, and total transfer volume surpassing the combined volume of Visa and Mastercard in 2024. The market is dominated by fiat-backed stablecoins, with the US dollar being the most common peg.

Issuers of fiat-backed stablecoins often establish a reserve fund holding real-world assets. So, if a stablecoin is backed by the U.S. dollar, the issuer might hold $100 million to support 100 million stablecoins. When a user wants to redeem their stablecoin, the issuer can draw from this reserve to provide the equivalent amount of fiat currency.

Stablecoins offer several key benefits.

• Reduced transaction fees: Many cryptocurrency exchanges skip the fees for users converting to or from stablecoins. Instead of cashing out into U.S. dollars (and racking up fees each time), traders can park their funds in stablecoins right on the exchange. This lets them wait out market dips or jump on a rally without losing any purchasing power in the process.

• Hedging against volatility: By holding stablecoins, traders can protect their investments from the price swings inherent in the crypto market.

• Passive income opportunities: Some stablecoins allow users to earn interest through staking or lending. For example, Coinbase offered a 4.1 percent reward to users who held USDC on the platform in July 2025.

While stablecoins offer significant advantages in stability and utility, they are not without risks. Centralized stablecoins like USDT and USDC can be frozen or burned by their issuers for regulatory compliance, raising concerns about user autonomy.

Sufficient reserves ensure that stablecoins can maintain their peg even during periods of market volatility. Without backing, a stablecoin can fall victim to runs, in which investors rush to redeem their tokens, potentially toppling the entire system.

Among the riskiest types of stablecoins are algorithmic stablecoins like USDD, which rely on market incentives and algorithms to maintain their value, but aren’t backed by real assets.

Algorithmic stablecoins, which rely on supply adjustments rather than reserves, are particularly vulnerable to "death spiral" events where a loss of confidence leads to a rapid de-pegging and collapse. Algorithmic stablecoins rely on technical mechanisms, such as adjusting the supply of coins, to keep the price stable. This approach is riskier because it’s more susceptible to market fluctuations and technical failures.

Crypto-backed stablecoins, such as Dai, are also high-risk. They maintain their dollar peg by using over-collateralized cryptocurrencies locked in smart contracts, making them vulnerable to the volatility of the underlying assets and technical flaws in the smart contracts.

Another type of high-risk stablecoin are synthetic stablecoins backed by derivatives and futures trading. This is because rather than the stablecoin, such as USDe, being pegged to cash or cash equivalents, futures are used to generate yield for investors while also attempting to maintain the token’s value.

TerraUSD, once the third-largest stablecoin by market cap, is a stark example of the pitfalls of algorithmic stablecoins. TerraUSD relied on a complex system of arbitrage and other cryptocurrencies to maintain its 1:1 peg to the U.S. dollar.

However, in 2022, a sudden crash eroded confidence in the system, leading to a catastrophic collapse. As investors panicked and sold off their TerraUSD tokens, the price plummeted, and the peg broke and never recovered.

Fiat-backed stablecoins are considered safer than some other stablecoins because they’re backed by reserves of cash or government bonds.

Regulatory scrutiny is also increasing globally, with the United States passing landmark legislation in July 2025 to regulate US dollar-backed stablecoins, aiming to enhance consumer protection and market stability. Despite these challenges, stablecoins are poised to play an increasingly significant role in global financial systems.

The following are the top stablecoins in global use.

Tether (USDT): The largest stablecoin by market capitalization, with over $186 billion as of December 2025. It is pegged to the US dollar and backed by reserves, primarily consisting of low-risk U.S. Treasury bills.

USD Coin (USDC): The second-largest stablecoin, with a market capitalization of over $63 billion Issued by Circle, it is also pegged to the US dollar and backed by audited reserves.

Dai (DAI): A decentralized stablecoin issued by MakerDAO, backed by a basket of other cryptocurrencies held in overcollateralized smart contracts. It is designed to maintain a 1:1 peg with the US dollar without relying on a centralized issuer.

Ethena USDe (USDe): A stablecoin that uses a novel algorithmic mechanism combined with a treasury of US dollar-denominated assets to maintain its peg.

World Liberty Financial USD (USD1): A stablecoin issued by President Donald Trump family-backed World Liberty Financial, pegged to the US dollar.

First Digital (FDUSD): A stablecoin issued by First Digital, also pegged to the US dollar.

Securing Your Crypto Funds

Your cryptocurrencies are stored on the blockchains which you access with your crypto wallet. A seed phrase is a list of 12 or 24 simple words that gives you access to your crypto wallet. The words come from a fixed set of 2,048 terms, called the BIP39 word list, and are auto-generated when you open your wallet for the first time.

The word list is defined by the Bitcoin Improvement Standard 39 which ensures that the same seed phrase can restore a wallet across different compatible platforms and apps. You can think of a crypto seed phrase as a master key.

The reason seed phrases use words rather than code is practical. Long strings of numbers and letters are hard to store and easy to mistype. A short list of words is easier to write down, check, and recover later.

When you set up a wallet, the software generates a seed phrase automatically. From that phrase, each time you use your wallet, it derives the private keys needed to sign transactions. It does this using a standard cryptographic process defined by BIP39, which converts the phrase into a secure digital "seed" that generates your keys. The entire phrase acts as the starting point to generate your keys. These private keys control your crypto assets on the blockchain.

You don't need to see or manage the private keys directly — the wallet does that for you. If you lose your phone or computer, you can recover your wallet by entering the seed phrase into another wallet app that supports the same standard. The app will rebuild your keys and restore access to your funds.

You don't need to enter your seed phrase when you buy, sell, or send crypto. Instead, it's only used when you first set up your wallet or need to recover access to your funds. In traditional banking, a provider can help you reset access to your account. In crypto, you control your access. If you lose your seed phrase, you might not be able to recover any lost crypto funds.

This is why the seed phrase is so powerful. It's simple and portable. It's also why it creates such a vulnerability if you lose it — it's a single point of failure that blocks your ability to recover your wallet and crypto assets.

Seed phrase and private key refer to separate layers of protection for your crypto assets. A seed phrase is the backup to your wallet. It's a short list of words that can recreate your wallet and all the private keys linked to it. Because it is human-readable, it's designed to be written down and stored offline.

A private key is a long string of letters and numbers that gives direct control over a specific crypto address. A crypto address is like an account number. It's where your crypto is stored on the blockchain and where others can send funds to you.

Some wallets use one main address, while others can generate new addresses for each transaction to improve privacy. All of these are still linked to your wallet.

The private key is used to sign transactions on the blockchain. Every time you send crypto, your wallet uses it to prove that you own the funds. This process happens in the background — so, in most cases, you won't see or handle the key directly. If someone has access to your private key, they can move the funds linked to that address.

If you're a new crypto investor, knowing and protecting your seed phrase is a core part of your investment setup. Remember, there's no central authority that can reverse a transaction or restore access to your account if you lose it. If your seed phrase is lost or stolen, there's usually no way to recover your funds.

Storing your crypto seed phrase safely starts with choosing where to write it down and how to protect it over time. This is one of the most important steps in crypto security.

Don't store your seed phrase in a notes app, email, or screenshot. Online storage increases the risk of hacking. Instead, write it on a durable, physical medium. Paper can degrade, and ink can fade. Some investors use engraved metal backup plates to store their seed phrase because these can withstand fire and water damage.

Once you decide where to write down your seed phrase, think about where to keep it. This could be a safe, a lockbox, or another secure area in your home. Some people choose to store multiple copies in separate locations to reduce the risk of loss.

Never share it. No legitimate service will ask for your seed phrase. If someone asks for it, that's a red flag. Always treat it like a password that can't be reset. If someone gains access to it, they can control your crypto. This is a serious situation, and speed and awareness are your best tools. Here's what you can do.

Step 1: Act quickly. Transfer your funds to a new wallet as soon as possible. Use a wallet with a new seed phrase that hasn't been exposed. 

Step 2: Move on from the compromised wallet. Whatever you do, don't reuse the jeopardized wallet. Once a seed phrase is exposed, it's no longer safe — even if no funds have been taken yet.

Step 3: Review how it happened. Was the phrase stored online? Was it shared by mistake? Understanding the cause can help you avoid the same issue in the future.

Many beginners make similar mistakes when dealing with seed phrases -- like storing it on a phone or computer, taking a screenshot, sharing it for some scammy service "support," and losing the only copy of the seed phrase. These errors are easy to make but hard to reverse.

When All Else Fail: Manually Generate Your Own Seed Phrase

To manually generate a secure crypto seed phrase, you should use offline analog methods to create true randomness, such as rolling dice, flipping coins, or selecting words from a printed BIP39 word list. This process avoids trusting a wallet's internal random number generator, which may be compromised or predictable.

The manual generation process typically involves these critical steps:

• Generate Entropy: Roll dice (e.g., 99 times for 256 bits) or flip coins to create a random binary string. Alternatively, physically pick 23 words from a list of 2048 options.

• Calculate Checksum: Use an air-gapped computer (no internet connection) and tools like the Ian Coleman Mnemonic Code Converter or SeedSigner to compute the checksum for your entropy or selected words.

• Derive Words: The tool converts the binary entropy and checksum into 12 or 24 decimal numbers, which correspond to the final BIP39 words of your seed phrase.

• Verify and Backup: Enter the generated phrase into an offline wallet like Sparrow Wallet to verify consistency, then engrave the words onto a metal backup plate and destroy all paper records.

Never use online seed phrase generators, as they expose your private keys to malicious actors. If you must use software for the checksum calculation, download the tool (e.g., `bip39-standalone.html`) on a secure machine, disconnect from the internet, and run it locally.
