An Initial Coin Offering (ICO) is a crowdfunding event in which a blockchain start-up sells newly minted digital tokens to raise capital for product development. Think of it as the crypto cousin of a stock IPO—but without equity or voting rights.
Quick definition
Investors swap cash or crypto (usually ETH, USDT or BTC) for project tokens that may appreciate once the network launches or the asset lists on an exchange.

Maximal Extractable Value (MEV) is the “invisible tax” traders pay when block producers or bots reorder transactions for profit. Ethereum.org defines MEV as value captured “in excess of block rewards and gas fees” by including, excluding or reordering transactions. Flashbots calls the fallout a user-harming cost and built public tools to mitigate it. This guide explains MEV in plain English, shows how it hits your swaps, and gives you a concrete toolkit to protect yourself in 2025.
What Exactly Is MEV? When you submit a trade, it first sits in a public waiting room (the mempool). Bots scan that feed and can:
Frontrun you—jump ahead and buy first. Sandwich you—buy before and sell after your order, forcing you to eat the slippage.

A fresh policy debate is rippling through U.S. housing: should cryptocurrency holdings count as part of a borrower’s wealth when applying for a mortgage? An opinion piece at Cointelegraph captured the mood, arguing that crypto hasn’t “crashed” the American Dream so much as renovated it—opening a side-door to homeownership for self-directed, digital-native savers. The trigger is a move by the Federal Housing Finance Agency (FHFA)—the regulator for Fannie Mae and Freddie Mac—to explore how crypto assets might be considered in mortgage applications, a shift from years of exclusion toward potential integration.
The idea is simple but powerful: if a household’s net worth includes digital assets—Bitcoin, Ether, dollar-stablecoins—shouldn’t part of that be recognized when lenders assess capacity and reserves?

Trading Insights: Memecoin Trading vs Crypto Trading
Memecoins have evolved from internet jokes into a high-beta corner of digital-asset markets. They move fast, live largely on-chain, and rely on attention cycles—very different from trading established assets like BTC or ETH. Understanding those differences can help you decide when to speculate, when to step aside, and how to execute more safely.
Below, we compare market structure (DEX vs. CEX), volatility patterns, on-chain execution risks like MEV, and common fraud vectors—with a practical checklist you can use before you press “swap.”
What makes a memecoin a memecoin?
“Memecoin” is a catch-all for tokens born from internet culture rather than a concrete utility roadmap.

Digital Gold Trading Insights: PAXG vs XAUT vs QGOLD
Tokenized gold bridges two worlds: the stability of bullion and the flexibility of crypto rails. Instead of opening a metal account or wiring to a bullion desk, you hold a token that represents title to vaulted gold and can be sent 24/7 across public blockchains. But not all gold tokens are alike. Issuers differ on custody, redemption, audits/disclosures, jurisdiction/regulation, and market access—differences that directly impact your risk.
Below is a side-by-side, source-backed guide to the three tickers you’ll encounter most often in 2025 conversations: PAXG (Pax Gold), XAUT (Tether Gold), and QGOLD (Quorium).
How tokenized gold works
At a high level, each token is intended to equal a pro-rata claim on London Good Delivery bullion held by a custodian.

Trading Insights: A Strategy That Delivered a 220× Crypto Win
A tiny bankroll, a giant return
A crypto trader has become the latest legend of “small stack, big brains.” According to Cointelegraph’s breakdown, the wallet ran a high-frequency, delta-neutral market-making bot on the decentralized perpetuals exchange Hyperliquidand, over roughly two weeks, parlayed a $6,800 working balance into $1.5 million in realized profit. The reported edge? Harvesting maker fee rebates at massive scale while keeping market exposure extremely tight.
Cointelegraph’s analysis pegs the strategy’s highlights as follows: cumulative trading volume above $20.6 billion, roughly $1.4 billion turned over in the key two-week stretch, maximum drawdown of ~6.48%, and net delta kept under $100,000 throughout—far closer to quant discipline than casino-style punts.

Looking for passive crypto income without day-trading? You’ve got more options than you did a year ago. Between spot crypto ETFs, staking-enabled ETPs (mainly in Europe), and covered-call crypto ETFs that distribute option premium, investors can now build a diversified income stream from regulated products. Below is a grounded, source-backed guide to crypto index funds, crypto ETFs, and how they can (and can’t) generate yield in 2025.
First principles: index funds vs. ETFs
Index funds passively track a rules-based basket (e.g., the 10 largest coins). U.S. investors can access vehicles like the Bitwise 10 Crypto Index Fund (BITW) and Grayscale Digital Large Cap Fund (GDLC) via brokerage accounts—these are publicly traded products offering diversified exposure, though fee structures and discounts/premiums to NAV matter.

Curious how miners make money securing Bitcoin? The short answer: miners bundle transactions into blocks and compete to add those blocks to the blockchain. When a miner (or, more commonly, a mining pool) wins, they collect two income streams—the block subsidy (newly issued BTC) plus transaction fees from the transactions in that block. Over time, the subsidy shrinks via “halvings,” while fees are expected to matter more.
Below is a practical walkthrough—from first principles to real-world payout schemes—so you can understand the economics before you ever plug in an ASIC.
What mining actually does
Mining is Bitcoin’s way to order transactions, secure the ledger, and issue new coins. In proof-of-work (PoW), miners repeatedly hash a block header until they find a nonce that produces a hash below the network’s target.

If you’ve ever asked “what is a stablecoin?” think of it as a digital dollar (or euro) that lives on a blockchain. Unlike Bitcoin or Ether, stablecoins aim to track a stable asset—usually USD—with mechanisms that keep the price near $1. They power crypto trading, cross-border payments, and increasingly mainstream fintech rails. Central banks and watchdogs study them closely because design choices (and reserves) determine how “stable” they really are.
What does a stablecoin actually do? In practice there are three big families:
Fiat-reserve (custodial) stablecoins A company issues tokens and holds cash-like reserves (T-bills, bank deposits). Customers can mint/redeem 1:1, and market-makers trade away tiny price gaps. This is the model used by USDT and USDC, which publish attestations about their reserves.

Layer-2 (L2) is how Ethereum scales without breaking its security model. Instead of cramming every transaction on the base chain (Layer-1), L2 systems process activity off-chain or in a separate environment, and then anchor results back to Ethereum. That design makes apps faster and cheaper while still inheriting strong L1 security guarantees. If you’ve heard terms like optimistic rollups, ZK-rollups, state channels, validium/volition, or EIP-4844 blobs, this guide connects the dots in clear English and cites only reputable sources.
The big idea: move work off-chain, prove it on-chain
At a high level, L2s reduce load by executing transactions away from L1 and then posting enough data—and sometimes cryptographic proofs—back to Ethereum so anyone can verify results.

Beyond USDT & USDC: The Most Interesting Stablecoins in 2025
If your stablecoin playbook starts and ends with USDT and USDC, you’re leaving tools on the table. In 2025 there are more choices than ever, spanning fully reserved, bank-issued tokens, decentralized over-collateralized designs, and region-specific fiat pegs. This guide highlights the most interesting alternatives—what backs them, how they’re governed, and when they make sense for payments, DeFi, or treasury. (Not investment advice; always verify reserves and limits.)
Fully reserved, custodial USD stablecoins
PayPal USD (PYUSD) Why it’s interesting: PayPal’s consumer reach plus institutional-grade issuance. PYUSD is issued by Paxos Trust Company and publishes monthly attestations. It runs on Ethereum and Solana, and PayPal documents point to the Paxos transparency page for reserve details.

Crypto Scams & Hacks 101: Everything You Need to Know
Headlines love the drama—“another hack,” “another rug pull.” But the full story is more nuanced: blockchains can be secure, while the people and platforms around them are often the weak link. This 101 guide pulls together credible data, the most common attack patterns, and a practical defense stack you can implement today—no PhD required. For context, Cointelegraph recently spotlighted the gap between perception and reality and why better security literacy is the real adoption driver.
The numbers: how big is the problem?
Scams are still huge. Chainalysis estimates that known crypto scams received at least $9.9B on-chain in 2024, with “pig-butchering” romance/investment fraud rising ~40% year over year. That figure will likely grow as new illicit wallets are identified.

If you’ve used stablecoins, exchange tokens, or governance coins on Ethereum, you’ve already touched ERC-20—even if you didn’t know it. ERC-20 is the most widely used fungible token standard on Ethereum, defining the common rules wallets, exchanges, and apps expect. Thanks to that common language, your tokens “just work” across the ecosystem.
What “ERC-20” actually means
ERC-20 is a standard interface—a set of functions and events every compliant token contract must expose. The original spec (EIP-20) defines six required functions (totalSupply, balanceOf, transfer, transferFrom, approve, allowance) and two events (Transfer, Approval). Implementing these makes a token interoperable with wallets, DEXes, and other smart contracts.
Put simply: ERC-20 makes different tokens behave predictably.
