Frequently Asked Questions

Cryptocurrency is digital money that exists only online. Unlike the dollars in your bank account, no government or bank controls it. Instead, it runs on a network of computers around the world that work together to record and verify every transaction. You can use cryptocurrency to send money, make purchases, or hold it as an investment, all without going through a traditional bank.

When you send cryptocurrency to someone, that transaction gets recorded on a blockchain — a shared digital ledger that thousands of computers maintain simultaneously. No single person or company owns it. This setup is called decentralization. Because records are spread across many computers, no one can alter or delete them easily. Most cryptocurrencies also have a fixed or limited supply — and that scarcity, combined with demand, is a large part of what gives crypto its value.

Crypto carries real risks. Here are four to understand before you start:

Technology risk — Software can have bugs or vulnerabilities. Platforms get hacked.

Market risk — Crypto prices are highly volatile. A coin can drop 50% in days.

User error risk — Unlike a bank, there is no customer service to recover a lost password or a mistaken transfer. Errors are often permanent.

Scam risk — Fake projects, phishing links, and fraudulent platforms are common. If something sounds too good to be true, it usually is.

Understanding these risks before investing is more important than picking the right coin.

Here is a simple five-step overview:

Choose an exchange (CEX) — Pick a platform that is licensed. This is where you will convert regular money into crypto.

Make a deposit and purchase — Transfer funds from your bank account to the exchange, then buy your first cryptocurrency.

Choose a wallet — A crypto wallet lets you store and manage your coins independently from the exchange. Select one that suits your needs.

Load your wallet for DEX transactions — Transfer crypto from your exchange into your wallet to access decentralised exchanges, where you can trade directly without a middleman.

Swap from one crypto to another — On a DEX, you can exchange one cryptocurrency for another directly from your wallet.

There is no right number but one rule applies universally: never invest more than you can afford to lose entirely.

Crypto markets are unpredictable. Prices can fall sharply and stay down for long periods. Starting small lets you learn how exchanges, wallets, and transactions work without significant financial exposure.

Think of your first investment as the cost of education, not a path to quick returns. Once you understand how crypto works in practice, you can decide whether to invest more.

Crypto itself is not a scam. It is a technology that enables digital transactions without relying on banks or governments. Thousands of businesses, institutions, and developers build on it daily.

That said, scams exist within the crypto space, just as they did in the early days of the internet where fraudulent websites and fake online businesses were common but that did not make the internet itself illegitimate. The same logic applies here.

What matters is the distinction between the technology and the bad actors who exploit it. Approaching crypto with that separation in mind is a reasonable starting point.

Not every crypto project is trustworthy. Here are five warning signs to check before putting money into anything:

Anonymous founders — Legitimate projects are typically led by people with verifiable identities and track records. Unknown founders with no public presence is a red flag.

Guaranteed returns — No investment guarantees profit. Any project promising fixed or unusually high returns is almost certainly fraudulent.

No whitepaper — A whitepaper explains what a project does and how it works. The absence of one means there is nothing to scrutinise.

No audit — Reputable projects have their code reviewed by independent security firms. Unaudited smart contracts carry significant risk.

Pressure to act fast — Urgency is a manipulation tactic. Legitimate investments do not expire in 24 hours.

If a project raises more than one of these flags, treat it as a scam until proven otherwise.

Crypto carries several distinct categories of risk. Understanding each one helps you make more informed decisions.

Volatility — Prices can move dramatically in short periods. Assets that double in value can also halve just as quickly.

Custody risk — If you store crypto on an exchange and that platform fails or gets hacked, you may lose access to your funds. Holding your own keys reduces this exposure.

Regulatory risk — Governments around the world are still developing crypto legislation. Policy changes can affect the value or legality of certain assets in certain countries.

Liquidity risk — Smaller cryptocurrencies may be difficult to sell quickly, especially during market downturns. You may not always be able to exit a position at the price you want.

Smart contract risk — Many crypto applications run on code. If that code contains vulnerabilities, funds can be lost — and in most cases, there is no way to reverse it.

If a centralised exchange goes bankrupt, your funds held on that platform may be frozen or lost. Unlike a bank, most exchanges are not covered by government deposit protection schemes. You become an unsecured creditor, meaning you join a legal queue with no guarantee of recovering your assets.

This is called custodial risk. When your crypto sits on an exchange, the exchange technically holds it on your behalf. You do not directly control it.

The alternative is self-custody, which means moving your crypto into a personal wallet where you hold the private keys. This removes reliance on any third party. It also means you are solely responsible for keeping those keys safe.

That depends on your financial situation, risk tolerance, and time horizon. What is observable is this:

Crypto adoption continues to grow. Major financial institutions now offer crypto products to clients. Governments are developing regulatory frameworks rather than outright banning it. Stablecoins are being used for real-world payments and cross-border settlements at increasing scale.

None of that guarantees returns. But it does suggest that crypto is no longer a fringe experiment. Whether it belongs in your portfolio is a personal financial decision, ideally made with professional advice.

"Safe" is relative in crypto. No cryptocurrency is without risk. That said, some assets carry less risk than others based on three factors:

Market capitalisation — Larger, more established cryptocurrencies tend to be less susceptible to sudden collapse than smaller, newer ones.

Liquidity — Assets that are widely traded are easier to buy and sell without large price swings.

Track record — Cryptocurrencies that have existed through multiple market cycles have a longer history to evaluate.

These factors can help you assess relative risk but they are not guarantees. This is not investment advice. Before making any financial decision, consult a licensed financial adviser.

Both are the most established cryptocurrencies, but they serve different purposes. Here is how they compare:

Neither is objectively the better starting point. Bitcoin is simpler to understand. Ethereum has more active development and use cases. Your choice depends on what you are trying to learn or achieve.

Both approaches are valid, but they suit different people. Here is a direct comparison:

Most beginners underestimate how difficult trading is in practice. Long-term holding is generally the more straightforward approach for those just starting out.

Stablecoins are cryptocurrencies designed to maintain a fixed value, most commonly pegged to the US dollar. One stablecoin typically equals one dollar, regardless of broader market conditions.

This stability makes them useful in ways that volatile cryptocurrencies are not:

Cross-border settlement — Stablecoins can be sent across borders in minutes, without the delays of traditional banking infrastructure.

Dollar access — In countries with weak or unstable local currencies, stablecoins give individuals and businesses access to dollar-denominated value without a US bank account.

Treasury use — Companies operating internationally use stablecoins to move and hold funds efficiently, reducing exposure to currency conversion fees and slow settlement times.

Stablecoins do not speculate on price. They are infrastructure, a practical layer that makes crypto usable for everyday financial operations.

Yes, and for many use cases it is faster and cheaper than traditional methods. Here is how the two compare:

For individuals sending remittances or businesses settling invoices across borders, crypto rails offer a meaningful practical advantage. Stablecoins are particularly well-suited for this, as they remove price volatility from the equation.

For most routine transactions, companies still use banks. But crypto offers specific advantages in three areas:

Treasury diversification — Some companies hold a portion of their reserves in Bitcoin or stablecoins as a hedge against inflation or currency devaluation, reducing reliance on a single asset class.

Settlement efficiency — Paying suppliers, contractors, or partners across borders using crypto can be faster and cheaper than wire transfers, particularly in regions with limited banking infrastructure.

Emerging markets — In countries where banking access is unreliable, slow, or expensive, crypto provides an alternative payment and settlement layer that operates independently of local financial systems.

This is not about replacing banks entirely. It is about using the most efficient tool for each situation.
