Unlock Bitcoin Riches: How to Buy Bitcoin with Gift Cards and Skyrocket Your Crypto Game!

A Bitcoin halving, often called “the halvening,” is a pre-programmed event in Bitcoin’s blockchain protocol that cuts the reward for mining new blocks in half.

This happens approximately every four years, or every 210,000 blocks, to control the supply of new Bitcoins entering circulation.

With a fixed supply cap of 21 million BTC, halvings ensure Bitcoin remains a deflationary asset, making it scarcer over time, think of it like digital gold.

Why does this matter?

Historically, bitcoin halving dates have been followed by significant price surges, sparking excitement among investors.

But it’s not just about price—halvings impact miners, market dynamics, and even the broader crypto ecosystem.

Whether you’re an investor eyeing profits or a curious newbie exploring bitcoin halving dates history, understanding this event is crucial to making informed decisions.

What Is Bitcoin Halving?

Bitcoin halving is a pre-programmed event that occurs every 210,000 blocks (approximately every four years), as outlined by Satoshi Nakamoto, Bitcoin’s pseudonymous creator.

During each halving, the reward granted to miners for validating transactions and securing the network is reduced by half.

This event is central to Bitcoin’s monetary policy, steadily reducing the new BTC supply over time and making Bitcoin increasingly scarce.

Why Does Bitcoin Halving Matter?

1. Supply Control and Scarcity

What it is: Bitcoin halving reduces the reward for mining new blocks by 50%, which effectively cuts the rate at which new bitcoins are introduced into circulation.

Why it matters: This enforces Bitcoin’s scarcity, as the total supply is capped at 21 million BTC. Reduced supply with steady or increasing demand can lead to price increases.

2. Inflation Reduction

Before halving: More bitcoins are mined and added to circulation.

After halving: The rate of new supply drops, reducing the inflation rate of Bitcoin.

Impact: Investors often view this as a deflationary asset, similar to gold.

3. Mining Incentives and Network Security

Miner rewards drop: Since miners earn fewer bitcoins per block, their profitability can decline unless the BTC price rises.

Potential consequences: Some miners may shut down, especially those with high electricity costs.

This could lead to a temporary drop in network hash rate and slower block times until difficulty adjusts.Long-term: More efficient miners remain, potentially making the network more resilient,

Long-term: More efficient miners remain, potentially making the network more resilient.

4. Historical Price Trends

Past halvings (2012, 2016, 2020): Each has been followed by a major bull run in the price of Bitcoin within 12–18 months.

Why: Reduced supply + speculation = price rally.

Bitcoin Halving History

Here is a history of Bitcoin halving events — including their dates, block numbers, and block rewards:

What Is Bitcoin Halving?

Bitcoin halving occurs approximately every 210,000 blocks (roughly every 4 years).

It cuts the block reward for miners in half, reducing the rate at which new Bitcoins are created. This mechanism:

-Controls inflation

-Ensures Bitcoin’s capped supply of 21 million

-Historically precedes major price rallies (but not guaranteed)

What Happens After Each Bitcoin Halving?

Each halving intensifies Bitcoin’s scarcity as fewer new coins are introduced into circulation.

This supply shock, coupled with growing global adoption, tends to drive market cycles historically characterized by price rallies, miner adaptation (as older, less efficient operations retire), and heightened media focus. However, several factors modulate these effects:

-Market Sentiment: Investor confidence can accelerate post-halving rallies.

-Macroeconomic Events: Global crises or liquidity changes can mute or inflate responses.

-Institutional Flows: ETF approval and corporate adoption play expanding roles.

-Mining Economics: Hashrate and energy costs can cause miner shakeouts, impacting network health.

Over time, halving events have less effect on absolute Bitcoin emission but greater psychological and narrative power, continuing to define Bitcoin’s investment story.

In the United States or Europe, Bitcoin is often viewed as a speculative asset—something you buy in hopes of getting rich. But for millions of people in the "Global South" (developing nations), the narrative is completely different.

In countries grappling with political instability and economic mismanagement, Bitcoin isn't a gambling chip; it is a survival tool. It is the only functioning bank account they have. While the West debates regulations, the developing world is leading the charge in actual, on-the-ground adoption. Here is how Bitcoin is countering inflation and reshaping economies in the third world.

The Trap of Hyperinflation

The primary driver of crypto adoption in countries like Argentina, Turkey, Venezuela, and Nigeria is hyperinflation.

When a government prints money recklessly to pay off debts, the value of the local currency collapses. Savings are wiped out overnight.

• The Reality: Imagine working for a month, getting paid on Friday, and needing to spend 100% of your paycheck by Saturday morning because prices will double by Monday.
• The Bitcoin Fix: Bitcoin offers an exit strategy. Because its supply is fixed at 21 million, it cannot be debased by a central bank. Citizens convert their rapidly depreciating fiat currency into Bitcoin (or stablecoins) to preserve the purchasing power of their hard-earned labor.

Banking the Unbanked

According to the World Bank, nearly 1.4 billion adults worldwide are "unbanked." They have no access to a checking account, credit card, or loan. Traditional banks see these people as "too poor" or "too risky" to service.

Bitcoin solves this through technology leapfrogging. Just as many African nations skipped building landlines and went straight to mobile phones, they are now skipping brick-and-mortar banks and going straight to mobile money.

• No Permission Needed: You don't need a passport, a utility bill, or a minimum balance to open a Bitcoin wallet. You just need a smartphone and an internet connection.
• Global Access: A farmer in rural El Salvador can participate in the same global financial network as a hedge fund manager in New York.

Killing the Remittance Tax

One of the biggest industries in the developing world is remittances—money sent home by migrant workers to their families.

Traditional services like Western Union or MoneyGram are notoriously predatory, often charging fees of 10% to 20% for cross-border transfers. They are also slow, taking days to settle.

• The Crypto Solution: Using the Bitcoin Lightning Network or stablecoins, a worker in Dubai can send money to their family in the Philippines instantly for a fraction of a penny. This puts more money directly into the pockets of the people who need it most, boosting the local economy rather than lining the pockets of a middleman.

Resisting Financial Censorship

In many authoritarian regimes, the banking system is a weapon. Governments can freeze the accounts of protesters, political dissidents, or anyone they dislike.

Bitcoin offers financial sovereignty. Because the network is decentralized, no dictator can freeze a Bitcoin wallet. It allows activists and citizens to transact freely, even in the face of government oppression. This was clearly demonstrated during protests in Nigeria and Belarus, where crypto became the primary funding method for resistance movements.

Conclusion

For the developing world, the debate over whether Bitcoin has "intrinsic value" is irrelevant. The utility is undeniable. It is protecting savings from inflation, connecting the unbanked to the global economy, and lowering the cost of moving money. Bitcoin is democratizing finance in a way that the traditional banking system never could.

Cryptocurrency continues to be a hot topic in 2025, but not every coin is a winner. While Bitcoin ended 2024 strong, many altcoins faced steep declines, earning the title of the worst cryptocurrency of the year. If you’re wondering what is the worst cryptocurrency or want to know the worst performing cryptocurrency to avoid, this article breaks down the biggest crypto losers of 2024 and what you should watch out for.

The Worst Cryptocurrency Names and Performers of 2024

The crypto market hit a total cap of $3.5 trillion at the start of 2025, showing overall growth. However, many altcoins struggled to keep up, with some losing over 50% of their value. These worst cryptocurrency names often share common problems: weak technology, poor management, and fierce competition.

Here are some of the worst-performing cryptocurrencies in 2024:

Arbitrum (ARB)

Arbitrum, once a promising Layer 2 scaling solution, suffered a massive 57.7% drop in 2024. Increased competition and scalability issues left it struggling to maintain investor confidence. Its failure to innovate quickly made it one of the worst cryptocurrencies last year.

Polygon (MATIC)

Polygon, another Layer 2 solution, fell by nearly 40%. Despite past success, it faced stiff competition and ongoing scalability problems. These challenges pushed Polygon into the worst performing cryptocurrency category for 2024.

Lido DAO (LDO)

Lido DAO, a decentralized staking platform, dropped 37.9% amid rising regulatory uncertainty and fierce competition in the staking sector. These factors made it one of the worst cryptocurrency names to hold last year.

Avalanche (AVAX)

Avalanche’s 23.7% decline was driven by a slowdown in developer activity and difficulties attracting decentralized apps (dApps). Despite its reputation, Avalanche became one of the worst performing cryptocurrencies in 2024.

Why These Cryptos Became the Worst Cryptocurrency

Several factors contributed to these coins’ poor performance:

• Increased competition: Newer, more efficient solutions stole market share.
• Scalability issues: Many struggled to handle growing user demand.
• Regulatory pressure: Uncertainty scared off investors, especially in DeFi and staking.
• Lack of innovation: Failure to adapt quickly led to loss of confidence.

The Worst States for Cryptocurrency Trading

If you’re trading in the U.S., be aware that states like New York and Texas have stricter crypto regulations. These can limit your access to certain coins or exchanges, making it harder to trade safely. Always check your state’s crypto laws before investing.

How to Avoid Investing in the Worst Cryptocurrency

Let's be honest. You've heard the words "coin" and "token" used almost interchangeably, and it's confusing. Is Bitcoin a coin or a token? What about Shiba Inu? Does it even matter?

It absolutely matters, and it's one of the most common hurdles for newcomers. But I have good news: the difference is actually very simple once someone explains it clearly. Let me be that person for you.

The Direct Answer

Here is the single most important distinction you need to remember:

• A coin operates on its own, native blockchain.
• A token is built on someone else's existing blockchain.

That's it. That's the core of it. Now, let's use a simple analogy to make this unforgettable.

The "Highway vs. Car" Analogy

Think of a blockchain as a massive, public highway system.

A Coin (like Bitcoin or Ethereum) is the highway itself. It is the fundamental infrastructure. It has its own rules, its own security, and its own native currency (the "coin") that is used to pay for tolls (gas fees) and keep the system running.

A Token (like Uniswap, Chainlink, or Shiba Inu) is a car that drives on that highway. The token doesn't need to build its own road system; it leverages the security and infrastructure of the existing highway (the blockchain) to operate.

Let's Break Down a "Coin"

A cryptocurrency coin is the native asset of its own blockchain. It's created directly by the protocol of that blockchain.

• Primary Purpose: Coins are often designed to function as a form of money. They are used as a store of value (like digital gold) or a medium of exchange to pay for things.
• Utility: On smart contract platforms like Ethereum, the native coin (ETH) is also used to pay for transaction fees, known as "gas." You can't use the Ethereum network without its native coin.
• Examples:
• Bitcoin (BTC) on the Bitcoin blockchain.
• Ether (ETH) on the Ethereum blockchain.
• Solana (SOL) on the Solana blockchain.

And What About a "Token"?

Tokens are created by projects that build applications on top of an existing blockchain. They are much easier and cheaper to create because the project doesn't have to build a whole new blockchain from scratch.

• Primary Purpose: Tokens usually represent a specific utility or asset within a particular project or application. They can represent anything:
• Utility Tokens: Grant you access to a service (e.g., Filecoin's FIL token for
       decentralized storage).
• Governance Tokens: Give you voting rights in a project's future (e.g., Uniswap's
       UNI token).
• Security Tokens: Represent ownership in a real-world asset (this is a more
       advanced topic).
• Meme Tokens: Have value primarily driven by community and hype (e.g.,
       Shiba Inu, which is an ERC-20 token on the Ethereum blockchain).

The most famous and common type of token is the ERC-20 token, which is the standard for creating tokens on the Ethereum blockchain.

Why This Matters for You as an Investor

Understanding this difference is crucial for your research.

• When you evaluate a coin, you are betting on the success and adoption of its entire blockchain infrastructure. You're asking, "Will this highway become a major city?"
• When you evaluate a token, you are betting on the success of a specific project or application, and on the health of the blockchain it's built on. You're asking, "Is this a good car, and is it driving on a safe and busy highway?"

Now you know one of the most fundamental concepts in the crypto world. [To learn more about other core topics, read our full guide to Cryptocurrency Concepts].

For years, traditional investors have watched the cryptocurrency market from a distance, intrigued by its potential but hesitant about the complexities of wallets, keys, and unregulated exchanges. The launch of spot Bitcoin ETFs, particularly the Fidelity Wise Origin Bitcoin Fund (FBTC), has fundamentally changed the landscape. It represents a bridge between the world of traditional finance and the new digital economy. As your guide, I'll walk you through exactly what the Fidelity Bitcoin ETF is, its advantages, and the critical trade-offs you need to understand.

What Is the Fidelity Bitcoin ETF (FBTC)?

The Fidelity Bitcoin ETF, which trades under the ticker symbol FBTC, is a regulated financial product that allows you to gain exposure to the price of Bitcoin in a standard brokerage account. It is a "spot" ETF, which is a crucial distinction. This means the fund's manager, Fidelity, actually buys and holds real Bitcoin as the underlying asset for the fund. The value of each share of FBTC is designed to track the price of Bitcoin, offering investors a familiar, stock-like way to invest in the digital asset.

The Key Advantages for a Traditional Investor

The appeal of FBTC for many investors is not about crypto; it's about convenience and trust. The primary benefit is that you can buy and sell shares of FBTC right alongside your other stocks and bonds in your existing Fidelity, Schwab, or other brokerage account. There is no need to sign up for a new crypto exchange, create a digital wallet, or manage complex private keys. Furthermore, it is a regulated product offered by one of the most trusted names in finance, which provides a level of comfort and security that many investors require.

The Trade-Off: Understanding "Not Your Keys, Not Your Coins"

While the convenience is undeniable, it comes with a fundamental trade-off that is at the heart of the cryptocurrency ethos. When you buy shares of FBTC, you own a security that represents Bitcoin, but you do not own the actual Bitcoin itself. You are trusting a custodian (in this case, Fidelity Digital Assets) to hold the Bitcoin on your behalf. This brings us to the famous crypto mantra: "Not your keys, not your coins." Because you don't control the private keys, you cannot withdraw your Bitcoin to a personal wallet or use it for transactions on the blockchain. You have price exposure, but you do not have self-custody or direct ownership of the underlying asset. Additionally, like all ETFs, FBTC comes with an annual management fee (an expense ratio) that is deducted from the fund's assets.

Who Is the Fidelity ETF For?

The Fidelity Bitcoin ETF is an excellent solution for a specific type of investor: one who wants to allocate a portion of their traditional portfolio to Bitcoin for price exposure, and who places the highest value on convenience and regulatory familiarity. It is for those who are comfortable with the "IOU" model of asset ownership and prefer to have a trusted institution manage the complexities of custody.

The Alternative: The Path to Direct Ownership

For those who are drawn to the core principles of cryptocurrency—such as self-sovereignty, decentralization, and the ability to be your own bank—the path is different. The alternative is to buy and hold actual Bitcoin on a secure, dedicated platform. This approach eliminates management fees and gives you full control and ownership of your asset.
