If you’ve ever asked yourself, how many bitcoins are there in the world? you’re in the right place. Whether you’re just starting out in cryptocurrency or looking to deepen your understanding, knowing Bitcoin’s total supply is key to grasping its value and future potential. Let’s break it down simply and clearly.

What’s the Total Supply of Bitcoin?

Bitcoin has a fixed total supply of 21 million coins. This means there will never be more than 21 million bitcoins in existence. As of today, about 19.5 million bitcoins have already been mined and are in circulation. The rest—around 1.5 million—are still waiting to be mined over the coming decades.

This cap is a core part of Bitcoin’s design, created by its founder, Satoshi Nakamoto, to mimic the scarcity of precious metals like gold. This scarcity helps Bitcoin maintain its value and protects it from inflation, unlike traditional fiat currencies such as the US dollar, which can be printed endlessly by central banks.

Why Does Bitcoin’s Supply Matter?

The limited supply makes Bitcoin a unique digital asset. Here’s why it’s important:

• Scarcity Creates Value: Just like gold, Bitcoin’s limited quantity means it can’t be devalued by creating more coins. This scarcity is a big reason many investors see Bitcoin as a store of value or “digital gold.”
• Inflation Hedge: Unlike fiat currencies that lose purchasing power over time due to inflation, Bitcoin’s fixed supply offers protection against this. It’s why people in countries with unstable currencies often turn to Bitcoin.

How Are New Bitcoins Created?

New bitcoins enter circulation through a process called mining. Miners use powerful computers to solve complex math problems that validate Bitcoin transactions. For their work, miners earn new bitcoins as a reward.

However, this reward gets cut in half approximately every four years in an event called “halving.” When Bitcoin launched in 2009, miners earned 50 bitcoins per block. After several halvings, today’s reward is just 6.25 bitcoins per block, and it will keep decreasing until all 21 million bitcoins are mined—expected around the year 2140.

What About Lost Bitcoins?

An important fact often overlooked is that millions of bitcoins are likely lost forever. Reasons include:

• Lost private keys or hardware wallets
• Forgotten wallets from early adopters
• Bitcoins sent to inaccessible addresses
• Owners passing away without sharing access

These lost coins reduce the effective circulating supply, increasing Bitcoin’s scarcity and potentially its value.

How to Keep Track of Bitcoin Supply?

If you want to check the current number of bitcoins in circulation, trusted platforms like CoinMarketCap, CoinGecko, or exchanges like Binance and BYDFi offer real-time data. These platforms also provide tools to help beginners learn and trade safely.

Final Thoughts: Why Knowing Bitcoin’s Supply Helps You?

Understanding how many bitcoins are there total helps you make smarter investment decisions, whether you’re trading on OKX, BitOasis, or just holding Bitcoin as a long-term asset. Scarcity drives value, and Bitcoin’s capped supply is what makes it special in the crypto world.

Ready to take control

What Are Crypto Indicators and Why Do They Matter?

Crypto indicators are mathematical calculations based on price, volume, or open interest data that help traders predict future market movements. Think of them as your trading GPS, guiding you through the chaos of Bitcoin, Ethereum, and altcoin markets. These tools are especially critical in 2025, with crypto markets becoming more volatile due to global economic shifts and regulatory changes. Whether you’re trading on Binance in Singapore, Coinbase in the U.S., or Kraken in the UK, technical analysis for crypto helps you:

1- Spot trends early to buy low and sell high.

2- Avoid emotional trading mistakes.

3- Identify oversold or overbought conditions to time your trades perfectly.

The Best Crypto Indicators You Need to Know in 2025

Here are the top indicators that can elevate your trading game, complete with practical tips for beginners and pros alike.

1. Relative Strength Index (RSI): Your Overbought/Oversold Compass

What is RSI in crypto? RSI is a momentum indicator that measures the speed and change of price movements on a scale of 0 to 100. It’s a favorite among traders because it signals when a cryptocurrency is oversold (below 30) or overbought.

What does oversold mean in crypto?

When RSI dips below 30, it suggests the asset is undervalued and may be due for a price rebound—perfect for buying opportunities. Conversely, an RSI above 70 indicates overbought conditions, signaling a potential price drop.

How to Use It: If you’re trading Bitcoin in USD on a platform like Coinbase, check the RSI on a 14-day period. If Bitcoin’s RSI drops to 25, it might be a great time to buy, assuming other indicators align.

Pro Tip: Combine RSI with support and resistance levels for more accurate signals.

2. Moving Average Convergence Divergence (MACD): Spotting Trend Reversal

sMACD is a trend-following indicator that shows the relationship between two moving averages of a crypto’s price. It’s perfect for identifying bullish or bearish trends.

How It Works: MACD consists of the MACD line, signal line, and histogram. When the MACD line crosses above the signal line, it’s a bullish signal (buy). A cross below is bearish (sell).

Use Case: Imagine you’re trading Ethereum in EUR on Kraken. A bullish MACD crossover could signal it’s time to enter a long position.

Pro Tip: Use MACD with a longer timeframe (e.g., 4-hour chart) to avoid false signals in volatile markets.

3. Bollinger Bands: Riding the Volatility Wave

Bollinger Bands measure market volatility and help traders identify overbought or oversold conditions. The bands widen during high volatility and contract during low volatility.

How to Use It: If a crypto’s price touches the lower band, it may be oversold—a potential buy signal. If it hits the upper band, it could be overbought, suggesting a sell.

Example: For altcoins like Solana traded in AUD on Binance, Bollinger Bands can help you time entries during tight consolidations.

Pro Tip: Pair Bollinger Bands with RSI to confirm signals and avoid false breakouts.

4. Volume: The Pulse of the Market

Volume measures how much of a cryptocurrency is traded in a given period. High volume often confirms the strength of a price trend.

• How It Works: Rising volume during a price increase signals strong buying interest, while low volume during a rally may indicate a weak trend.
• Use Case: If you’re trading XRP in JPY on Bitfinex and notice a price spike with low volume, it might be a false breakout—proceed with caution.
• Pro Tip: Use volume alongside other indicators like RSI or MACD for stronger confirmation.

5. Fibonacci Retracement: Finding Key Price Levels

Fibonacci Retracement helps traders identify potential support and resistance levels based on the Fibonacci sequence.

1- How It Works: Draw Fibonacci levels (23.6%, 38.2%, 50%, 61.8%) on a price chart to find where the price might reverse or consolidate.

For many, the idea of a savings account is simple: you deposit money, and the bank pays you interest. In the world of digital assets, a similar concept exists, often called a crypto savings account or crypto interest account. These services offer a compelling proposition: the ability to earn a passive yield on your crypto holdings, rather than letting them sit idle.

This guide will explain how these accounts work, where the yield comes from, and most importantly, the critical risks you must understand before you consider using one.

What Is a Crypto Interest Account?

A crypto interest account is a service, typically offered by a centralized company, that allows you to deposit your cryptocurrencies and earn regular interest payments, which are usually paid out in the same crypto you deposited. While it uses the familiar language of a "savings account," it is fundamentally different and does not have the same protections as a traditional bank account.

How Do These Accounts Generate Yield?

The interest, or "yield," you receive is not created out of thin air. It is generated primarily through two methods, both of which involve the platform putting your deposited assets to work.

Lending to Borrowers: The most common method is lending. The platform takes your deposited crypto and lends it out to other users, such as institutional traders or market makers, at a higher interest rate. The platform then pays you a portion of the interest it earns, keeping the difference as its profit.

Staking: For some cryptocurrencies that use a Proof-of-Stake (PoS) consensus mechanism, the platform may "stake" your deposited assets on the blockchain. This helps to secure the network, and in return, the network pays out staking rewards. The platform then passes a portion of these rewards on to you.

The Critical Risks You Must Understand

This is the most important section of this guide. The potential for high yield comes with significant risks that are not present in traditional banking.

No Government Insurance: Unlike a bank savings account, which is typically protected by government insurance like the FDIC or SIPC, crypto interest accounts have no such protection. If the company offering the service fails or goes bankrupt, your funds are not insured and can be lost completely.

Counterparty Risk: This is the risk that the company you entrust with your crypto (your "counterparty") will mismanage the funds or become insolvent. If the borrowers they lend to default on their loans, the platform may not be able to return your assets. The history of the crypto industry includes several major lending platforms that have failed, resulting in a total loss of funds for their users.

Market Risk: Even while you are earning interest, the underlying value of your deposited crypto can still fall. A 5% yield on an asset that drops 50% in value is still a significant net loss.

Where to Find Crypto Interest Accounts

These services are offered by two main types of platforms.

Centralized Finance (CeFi) Platforms: These are company-run platforms that provide a user-friendly, custodial experience. You deposit your crypto directly with the company, which manages the lending and staking process for you.

Decentralized Finance (DeFi) Protocols: These are more advanced, non-custodial alternatives that run on smart contracts. Users can lend their assets directly to a protocol and earn yield without a central intermediary. This method removes counterparty risk but introduces its own set of technical risks, such as smart contract bugs.

In the world of crypto, one question has become more important than any other: "Are my funds actually safe?"

After the shocking collapse of exchanges that appeared solvent, investors are rightfully demanding more transparency. This has led to the rise of a crucial security audit called Proof of Reserves (PoR).

If you've heard this term but aren't sure what it means, this guide is for you. We'll break down what a crypto reserve audit is, how it works, and—most importantly—what its limitations are.

Proof of Reserves Explained: "Show Me the Money"

At its core, Proof of Reserves is a simple idea: it's a verifiable audit designed to prove that a cryptocurrency exchange holds enough assets to cover all of its customer balances.

Think of it like a bank allowing a trusted, independent auditor to:

1. all the cash in its vaults.
2. all the money its customers have deposited.
3. that the cash in the vaults is equal to or greater than the customer deposits.

PoR is the crypto-native way of doing this, using the transparency of the blockchain.

How Does It Actually Work? The Two-Part Check

A proper proof of reserves audit isn't just a simple statement; it's a cryptographic process with two key parts:

Part 1: Proving the Exchange's Reserves

The exchange must publicly show all the wallet addresses it controls. Using the public nature of the blockchain, anyone can then independently verify the total amount of assets held in those wallets.

Part 2: Proving the Exchange's Liabilities (Customer Balances)

This is trickier, as customer balances must remain private. The solution is a clever cryptographic method called a Merkle Tree.

• The exchange takes a "snapshot" of all customer balances.
• It then builds a Merkle Tree, a cryptographic structure that combines all these balances into a single "root hash" – one piece of data that represents the total.
• You, as a customer, can then find your specific "branch" of the tree to verify that your balance was included in the total, without seeing anyone else's information.

If the total from Part 1 is greater than the total from Part 2, the exchange has passed the audit.

The Critical Question: Is Proof of Reserves Enough?

No. And it is vital that you understand the limitations.

Proof of Reserves is NOT a full financial audit. It proves the assets on hand at a specific moment in time. However, it does not show the exchange's liabilities or debts. An exchange could borrow a
massive amount of crypto to pass the audit, only to return it the next day.

While PoR is a massive step forward in transparency, it is a starting point, not a complete guarantee of solvency.

Your Role as a Savvy Investor

In today's market, choosing a trading platform is about more than just low fees and a wide selection of assets. It's about prioritizing security and transparency above all else.

Understanding concepts like Proof of Reserves is a key part of your due diligence. It shows you know what to look for and what questions to ask. The next step is to choose a platform that aligns with this security-first
mindset.

The Quiet Revolution: Unpacking the Real Meaning of  Onchain

Lately, it feels like you can’t wander through the digital corridors of crypto without hearing the term. It’s whispered in Discord channels, debated fiercely on Crypto Twitter, and proudly displayed on the homepages of the most innovative DeFi and NFT platforms. The word is  onchain.

But what does it truly mean? Beyond the buzzword, why does this concept feel so fundamental, so powerful, that it’s becoming the central pillar of the entire Web3 movement? If you’ve ever felt that the explanation "it's stored on the blockchain" was a little too neat, a little too simple, you’re right. Understanding onchain is about understanding a profound shift in how we think about trust, transparency, and our very interaction with the digital world.

So, What Exactly Does Onchain Mean? Let's Get Concrete.

At its heart, onchain  describes an action that is recorded, verified, and permanently etched into the shared, public ledger of a blockchain. Think of this ledger not as a dusty book in a bank vault, but as a living, breathing, unchangeable digital history book that is copied across thousands of computers worldwide.

When you send Bitcoin to a friend, that transaction isn't just a message between you and them. It's a broadcast to the entire network. A global network of miners or validators races to solve a cryptographic puzzle to prove the transaction is legitimate—that you have the coins, you haven't already spent them, and you’ve signed the transaction correctly. Once verified, your transaction is grouped with others into a  block. This block is then cryptographically linked to the one before it, and the one before that, all the way back to the very first block. This chain of blocks—the blockchain—becomes an immutable record.

That entire process, from broadcast to permanent inclusion, is an onchain transaction. It’s transparent because anyone in the world can open a tool like Etherscan and see it. It’s secure because altering it would require an impossible amount of computational power to rewrite the entire chain. And it’s trustless because you don’t need to rely on a bank, a government, or a company to make it happen. The network, through consensus and cryptography, does the work.

The Great Divide: Onchain Life vs. Off-Chain Convenience

To truly grasp the weight of  onchain,  we need to contrast it with its counterpart: off-chain.  This is where the philosophical divide becomes crystal clear.

Imagine you’re trading stocks on an app like Robinhood or trading crypto on Coinbase. You buy, you sell, the numbers on your screen go up and down. But where is this actually happening? In most cases, these trades are occurring within the company's own private, internal ledger. They are updating their own database to reflect your new balance. It’s fast, it’s cheap (or feels free), and it’s convenient. But it’s fundamentally a promise. You are trusting that Robinhood or Coinbase is accurately keeping track and will honor your balance when you decide to withdraw. This is the world of off-chain.

Decentralized applications (dApps) like those in the DeFi and NFT space need to access and display a massive amount of data from the blockchain. However, getting this data directly from a blockchain is like trying to find a specific book in a library with no catalog system; it is slow, inefficient, and resource-intensive. The Graph was created to solve this fundamental problem.

What is The Graph?

The Graph is often called the 'Google of Blockchains'. It is a decentralized protocol for indexing and querying data from blockchains, starting with Ethereum. It allows developers to easily search for, find, and use blockchain data without needing to run their own complex infrastructure. In essence, it creates a well-organized, global catalog for the public data stored on blockchains, making it easily accessible for everyone.

How The Graph Works: The Network Roles

The Graph's ecosystem is powered by several key participants who work together to ensure data is indexed accurately and served quickly.

Subgraphs

A subgraph is a custom, open API that defines what data to index from a blockchain and how to store it. Each dApp can build its own subgraph to track the specific data it needs, such as NFT ownership records or DeFi trade histories.

Indexers

Indexers are the node operators of the network. They stake The Graph's native token, GRT, to provide indexing and querying services. They run the software that processes the information defined in a subgraph and are rewarded with GRT for their work.

Curators

Curators are participants who signal which subgraphs are high-quality and should be indexed by the network. They stake GRT on a specific subgraph to indicate their belief in its importance and accuracy, earning a portion of the query fees for that subgraph.

Delegators

Delegators are individuals who want to contribute to securing the network without running a node themselves. They can delegate their GRT to an existing Indexer and earn a portion of that Indexer's rewards and fees.

The Role of the GRT Coin

The GRT coin is the essential utility token that coordinates the entire Graph network. It is an ERC-20 token on the Ethereum blockchain and is used for several critical functions. It is used for staking by Indexers and Curators, for delegating by Delegators, and as the means of payment for dApps that consume the data services. This creates a complete economic cycle where all participants are incentivized to act in the best interest of the network.

The Investment Perspective

Investing in The Graph's GRT coin is a bet on the future growth of the entire Web3 and dApp ecosystem. The Graph is not a dApp itself; it is a piece of critical, foundational infrastructure that nearly all dApps will need to operate efficiently. As the number of dApps grows, the demand for The Graph's data indexing services is expected to grow as well. This positions The Graph as a "picks and shovels" investment for the broader adoption of decentralized technology.
