Crypto basics, and why people invest

This page is for South Africans who keep hearing about crypto assets and want the subject explained once, calmly, in ordinary language. It is an information page, not advice: nothing here is a recommendation to buy or sell anything, and no asset class guarantees a return. Where an example is given, it is an illustration, not a forecast.

What cryptocurrencies are

A cryptocurrency is a digital asset that moves between holders over a network of computers without a central issuer standing in the middle. The shared record that keeps track of who holds what is called a blockchain: a running ledger, copied across thousands of machines, where each batch of new transactions is checked by the network before it is added. Nobody can quietly edit an old entry, because every copy would disagree with the forgery.

The value of any crypto asset, like anything traded, comes down to supply and demand. Some assets have a fixed maximum supply written into their rules; others issue new units on a schedule. Demand rises and falls with usefulness, sentiment and liquidity. That combination, scarce supply plus shifting demand, is why prices move the way they do.

Term	Plain meaning
Digital asset	Anything of value that exists only in electronic form, including cryptocurrencies.
Blockchain	The shared, replicated ledger that records who holds what and who sent what to whom.
Wallet	A tool that holds the keys used to sign transactions. The keys, not the wallet file, are what matter.
Exchange	A venue where rand or other currencies are traded for digital assets.
Liquidity	How easily an asset can be bought or sold near the displayed price.

How a transaction works, step by step: you sign a transfer with your private key, the network's computers check the signature and your balance, the transaction joins a batch, the batch is added to the shared ledger, and the recipient's balance updates. Minutes later it is irreversible, which is why fraudsters love it and why you should double-check every address.

Why prices change

Crypto prices are set by continuous trading, and the forces behind them are less mysterious than they look. Trading volume tells you how much conviction sits behind a move: a price jump on thin volume is a rumour, the same jump on heavy volume is a decision. News moves prices within minutes, from regulatory announcements to a large institution taking a position, and so does sentiment, the market's collective mood, which swings between greed and fear on shorter cycles than most other asset classes.

Macroeconomic factors matter more than early crypto adopters expected: interest rates, the dollar's strength and risk appetite in global equity markets all wash into crypto prices. For a South African, the rand itself is part of the picture, since a weakening rand changes the rand price of an asset even when its dollar price stands still.

Factor	What it does to price
Trading volume	Confirms or questions a move. Moves on low volume often reverse.
News and regulation	Sharp, fast repricing in both directions.
Investor sentiment	Drives overreactions in calm markets and panics in stressed ones.
Economic conditions	Rates and risk appetite set the tide everything floats on.
Rand strength	Changes rand prices of assets quoted in dollars.

What volatility means for you

Volatility is how much and how quickly a price moves. High volatility means large swings in short windows; low volatility means prices that drift. Neither is good or bad on its own: volatility is what creates trading opportunities, and it is also what turns small mistakes into large ones. A beginner should understand that a chart that can rise twenty percent in a day is a chart that can fall the same way.

Aspect	High volatility	Low volatility
Typical daily range	Several percent or more	A fraction of a percent
Opportunity	Frequent, large moves	Slow, smaller moves
Risk to a position	Losses can mount quickly	Losses accumulate slowly
Suitable stance	Smaller exposure, stricter limits	Larger positions can be tolerated

What to take from the table: size your positions to the volatility, not to your optimism.

What risk management is

Risk management is the practice of deciding, before you enter a position, how much you are prepared to lose on it. Its core principles are simple. Only commit money whose loss would not change your life. Diversify, so that one bad asset or one bad week does not sink everything. Set exposure limits per position and per asset class, and respect them even when the market tempts you. Review results on a schedule rather than in the heat of the moment.

The AfriLegacy AI platform gives you tools that support this discipline rather than replacing it: exposure parameters you set per strategy, a volatility brake that can pause trading when markets turn violently unstable, plain-language reports that show what each strategy did and what it cost, and a personal manager who helps you choose limits that suit your budget. What the platform does not do is make the decision for you or guarantee an outcome; the ceiling on what you risk is yours to set and yours to keep.

Questions beginners actually ask

Do I need to understand the technology to invest? No more than you need to understand an engine to drive. You should know what an asset is, where it trades, what it can do to your money and how to keep your account secure. The rest is specialist knowledge you can acquire gradually.

Can I start with a small amount? Yes. The Basic plan starts at From R4,500, and starting small is the correct way to learn how you personally react to gains and losses before more money is involved.

Is it like a savings account? No. A savings account preserves capital and pays modest interest; a trading balance can grow faster and can also shrink. Money you cannot afford to see fall in value belongs in the savings account, not here.

Why does the price on my screen differ between sites? Prices come from different trading venues at slightly different moments, and rand quotes add the exchange rate on top. Small differences are normal; large ones warrant a second look.

Where do I read about the risks in full? On our risk disclosure page, which every new client should read once, properly, before depositing.

Where to go next

If this page made the asset class clearer, two natural follow-ons are the Cryptocurrencies product page, which describes how the platform tracks and analyses these markets, and the Getting Started guide, which turns interest into a working, risk-limited setup in four steps.
