When Will Tech Layoffs Stop? Understanding IT and Big Tech Layoffs in 2025
As someone working in the tech industry in the U.S., I’m worried about the ongoing wave of IT layoffs and tech layoffs that seem to hit every few months. I’ve seen reports of big tech layoffs at companies like Microsoft, Amazon, and Meta, and it’s making me anxious about job security.
Are layoffs in tech still happening in 2025, or is there an end in sight? I want to know what’s driving these layoffs, if tech companies are still laying off, and when we might see some stability.
I’m also curious about how this affects opportunities in emerging fields like cryptocurrency or blockchain.The news about big tech layoffs is everywhere, and it feels like even profitable companies are cutting jobs.
I’m wondering if factors like AI adoption or economic shifts are to blame. For someone planning their career in tech, possibly in crypto markets like Bitcoin, what should I expect moving forward?

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].

2026-01-16 · 19 days ago0 0360What is Blockchain? A Beginner's Guide to the Digital Ledger
What Is Blockchain? The Unseen Revolution Changing Your World
Imagine a shared Google Doc. But this isn't an ordinary doc. When anyone adds a new paragraph, it's permanently locked in. You can't go back and edit a previous paragraph without everyone in the world who has a copy of the doc seeing a bright red flag. No single person controls it, yet everyone can trust its contents completely. This, in its simplest form, is the essence of blockchain.
It’s not just a technology for digital money; it's a new framework for trust in a distrustful world. It’s the silent engine under the hood of a new internet, often called Web3, and understanding it is no longer a luxury for tech enthusiasts—it's a necessity for anyone who interacts with the digital world.
The Core Idea: A Ledger Without a Leader
At its heart, a blockchain is a decentralized, digital ledger. Let's break that down.
1- Ledger: Think of it as a record-keeping book, like an accounting journal that logs transactions.
2- Digital: It exists on computers, not paper.
3- Decentralized: This is the game-changer. Unlike your bank's ledger, which is stored and controlled solely by the bank, a blockchain's ledger is distributed across thousands of computers worldwide (called "nodes"). Every single one has an identical copy.
This decentralization means there is no central point of failure. There's no CEO, no server room, no single company to hack, bribe, or shut down. To compromise the system, you'd need to simultaneously attack over 51% of all these computers, a task so astronomically difficult and expensive it's practically impossible for major blockchains.
The Magic of the Block : How the Chain is Built
So, how does this ledger actually work? It's all in the name: block and chain.
What is a Block in Blockchain?
Think of a block as a single, sealed page in that global ledger. This page contains three key things:
1- Data: This is the actual information. For Bitcoin, it's a list of transactions (e.g., "Alice sends 0.1 BTC to Bob"). For other blockchains, it could be lines of code for a smart contract or records of a product's journey through a supply chain.
2- Its Own Hash: A hash is like a unique, digital fingerprint. It's a long string of numbers and letters generated from the data inside the block. If even a comma changes in the data, the hash changes completely.
3- The Previous Block's Hash: This is the literal link in the chain. Every new block contains the hash of the block that came immediately before it.
This simple-sounding structure is what creates an unbreakable chain of trust. Let's say a hacker tries to alter a transaction in Block 50. This action will change Block 50's hash. But remember, Block 51 has a record of what Block 50's hash used to be. The moment the hash changes, the link between Block 50 and 51 is broken. The entire network sees this break and immediately rejects the fraudulent block.
To succeed, the hacker would need to recalculate the hash for Block 50, then Block 51, then Block 52, all the way to the very latest block—and do this faster than the rest of the honest network can add new blocks. On a massive blockchain like Bitcoin's, this is like trying to outrun the entire world in a race to solve a complex math problem. It's not just hard; it's computationally infeasible.
Why This Matters in 2025: Moving Beyond the Hype
For years, blockchain was synonymous with volatile cryptocurrency prices. But today, we're seeing its utility mature and solve real-world problems. It's moving from a speculative asset to the backbone of a new digital infrastructure.
Here’s where it’s making a tangible impact:
1- Finance (DeFi - Decentralized Finance): Imagine sending money across the globe, from the US to the Philippines, in seconds for a fraction of a cent, without needing a bank, a wire transfer, or a service like Western Union. This is the promise of blockchain in finance. It's creating a global, open financial system that anyone with an internet connection can access.
2- Supply Chains: Companies like Walmart use blockchain to track food products from the farm to the store shelf. In the event of a contamination scare, they can pinpoint the exact source in minutes, not days, preventing waste and ensuring safety.
3- Digital Ownership (NFTs and Digital Assets): Beyond the art hype, NFTs prove true ownership of a unique digital item on the blockchain. This is evolving to represent everything from concert tickets and in-game items to deeds for physical assets like houses.
4- Voting: While still emerging, blockchain-based voting systems offer the potential for fraud-proof, transparent, and verifiable elections, which could be transformative for emerging democracies.
A Practical Example: BYDFi and the World of Crypto Trading
For traders, this technology isn't abstract—it's the platform they use every day. This is where exchanges like BYDFi come into play.
BYDFi is an international digital asset exchange that leverages blockchain technology to provide a secure and user-friendly platform for buying, selling, and trading cryptocurrencies. It acts as a gateway, allowing users to enter this new financial ecosystem. On a platform like BYDFi, you can:
1- Trade a vast array of cryptocurrencies (like Bitcoin, Ethereum, and many others) against various fiat currencies and stablecoins.
2- Experience the benefits of decentralized finance through a regulated and accessible interface.
3- Maintain custody of your assets, giving you true ownership of your digital wealth, aligned with the core philosophy of blockchain.
Platforms like BYDFi demonstrate the practical application of blockchain, making the complex simple for the end-user and providing the tools to participate in this digital economy.
Busting Common Myths
1- Blockchain is only for Bitcoin. This is like saying the internet is only for email. Bitcoin was the first application. Now, blockchain is the foundation for thousands of projects, from decentralized social media to new forms of corporate organization (DAOs).
2- It's completely anonymous. It's actually pseudonymous. Transactions are publicly visible on the ledger, but they are linked to a digital wallet address, not directly to your real-world identity (unless that identity is revealed).
3- It's a solution looking for a problem. As the examples above show, it's already solving critical problems of trust, transparency, and efficiency in numerous industries.
The Road Ahead: A Future Built on Blocks
The journey of blockchain is just beginning. We are heading towards a future where our identities, assets, and contracts could live on decentralized networks, giving us back control from large tech corporations. While challenges remain—like scalability, energy consumption (though this is rapidly improving with new models like Proof-of-Stake), and regulatory clarity—the direction is clear.
Blockchain is more than a technology; it's a philosophical shift. It's the belief that we can build systems that are inherently fair, transparent, and resilient. It’s the quiet revolution building a new layer of trust for the digital age, and it's changing everything.
2026-01-16 · 19 days ago0 0196Ethereum Quantum Readiness: Is Your Crypto Safe?
Ethereum quantum readiness has moved from a theoretical debate to an urgent priority in 2026. As the network matures into the backbone of the global financial system it faces existential threats that have nothing to do with price.
Vitalik Buterin recently highlighted two concepts that define the future of the chain. These are the "Walkaway Test" and the threat of quantum computing. Understanding these concepts is essential for anyone holding ETH for the long term.
Key Takeaways:
- The "Walkaway Test" determines if a blockchain can survive if its founders and core developers suddenly disappear.
- Ethereum quantum readiness is the next major hurdle as quantum computers threaten standard encryption methods.
- Vitalik Buterin's roadmap is shifting focus toward "The Scourge" phase to secure the network against future threats.
What Is the Walkaway Test?
The Walkaway Test is a thought experiment proposed to measure true decentralization. It asks a simple question. If Vitalik Buterin and the entire core development team moved to a remote island and cut off all communication would the chain survive?
For most crypto projects the answer is no. They rely on their leaders to fix bugs and push updates. But for Ethereum the goal is to become a self-sustaining organism.
The protocol must be "finished" enough that it runs on autopilot. This ensures that no government or entity can pressure the leaders to change the rules because the leaders are no longer necessary.
How Does It Compare to Bitcoin and Solana?
When analyzing the "Walkaway Test" Ethereum sits in a unique middle ground compared to its rivals. Bitcoin passed this test over a decade ago when Satoshi Nakamoto vanished. Bitcoin is fully "ossified" meaning its code rarely changes and it requires no central leadership to survive.
On the other end of the spectrum are high-performance chains like Solana or BSC. These networks still rely heavily on their foundations and founders to drive innovation and fix outages. If their leaders walked away today the projects would struggle to coordinate upgrades.
Ethereum is the only major chain actively transitioning from a founder-led startup to an ossified public good. While it tackles Ethereum quantum readiness it is also deliberately decentralizing its own governance structure to catch up to Bitcoin's level of resilience.
Why Is Quantum Readiness So Critical?
The second pillar of survival is Ethereum quantum readiness. Current blockchain security relies on elliptic curve cryptography. This math is impossible for a normal computer to break but easy for a sufficiently powerful quantum computer.
If a bad actor develops a quantum computer before Ethereum upgrades its defenses they could theoretically steal user funds. They could reverse engineer private keys from public addresses.
This is why the Ethereum roadmap includes a phase known as "The Scourge." This phase is dedicated to implementing post-quantum cryptography. It ensures that the network remains secure even in a world where quantum computing becomes a reality.
How Does This Affect Your Investment?
For institutional investors Ethereum quantum readiness is a major due diligence checklist item. Trillions of dollars in tokenized assets cannot sit on a ledger that might be cracked in five years.
The push for these upgrades signals that Ethereum is transitioning from a "move fast and break things" startup to a "security first" global settlement layer. It prioritizes stability over new features.
This shift might make development feel slower but it makes the asset significantly more valuable as a store of trust. It builds a moat around the ecosystem that newer faster chains cannot match.
Is the Network Truly Decentralized Yet?
Not fully but it is getting there. The implementation of automated upgrades and client diversity helps.
We are seeing a move toward "ossification." This means the core rules of the protocol become set in stone much like the TCP/IP protocols of the internet. Once this happens the Walkaway Test will finally be passed.
Conclusion
The focus on Ethereum quantum readiness and the Walkaway Test proves that the developers are thinking decades ahead. They are building a system designed to outlive its creators and withstand the technological threats of the future.
This level of foresight is what separates blue-chip assets from temporary trends. Register at BYDFi today to invest in Ethereum and other future-proof assets on the Spot market.
Frequently Asked Questions (FAQ)
Q: When will quantum computers break crypto?
A: Estimates vary but most experts believe we are still 5 to 10 years away from a quantum computer powerful enough to break current blockchain encryption.Q: Will I need to move my ETH to a new wallet?
A: Eventually yes. When Ethereum quantum readiness upgrades go live users may need to transition to new address types that use quantum-resistant signatures.Q: What happens if Vitalik leaves Ethereum?
A: The price might react in the short term due to panic but the network would continue running. Thousands of independent developers now contribute to the code.2026-01-26 · 9 days ago0 082
