Understanding the world of digital currencies begins with grasping key fundamentals: how prices are determined, how market capitalization shapes rankings, and where to securely engage with this fast-evolving financial ecosystem. This guide breaks down everything you need to know about cryptocurrency prices, market caps, and how to safely invest in top digital assets.
How Cryptocurrency Market Cap Is Calculated
The market capitalization (or "market cap") of a cryptocurrency is calculated by multiplying its current price by its circulating supply. For example, if a digital currency has 10 million coins in circulation and each coin is valued at $50, its market cap would be $500 million.
Market cap is one of the most important metrics investors use to assess the relative size and stability of a cryptocurrency. Generally, assets with larger market caps—like Bitcoin and Ethereum—are considered more established and less volatile than smaller-cap coins.

Why Market Cap Determines Cryptocurrency Rankings
Cryptocurrencies are typically ranked by market capitalization. This ranking system helps investors compare digital assets objectively and identify which ones have broader market adoption.
On platforms like OKX, you can view a full list of cryptocurrencies sorted by market cap, price change (24-hour gain or loss), or other customizable filters. Whether you're exploring blue-chip cryptocurrencies or emerging altcoins, sorting by market cap gives you a clearer picture of each asset’s position in the global crypto landscape.
What Drives Cryptocurrency Prices?
Unlike traditional fiat currencies controlled by central banks, cryptocurrency prices are driven purely by supply and demand dynamics in the open market.
When more people want to buy a particular coin than sell it, demand exceeds supply—and the price rises. Conversely, when more holders are selling than buying, downward pressure pushes the price lower.
Several factors influence this balance:
- Investor sentiment (news, regulations, macroeconomic trends)
- Adoption rates (real-world use cases, merchant acceptance)
- Supply constraints (fixed issuance schedules, mining limits)
For instance, Bitcoin has a maximum supply cap of 21 million coins. This built-in scarcity mimics precious metals like gold and can contribute to long-term value appreciation as demand grows.
Fixed Supply and Scarcity: A Key Value Driver
Many digital currencies—especially Bitcoin—are designed with a fixed or predictable issuance schedule. This contrasts sharply with fiat money, which governments can print indefinitely, often leading to inflation.
Because these cryptocurrencies cannot be arbitrarily inflated, their scarcity becomes a core part of their value proposition. As adoption increases while supply remains limited or grows slowly, the potential for price appreciation rises—assuming demand remains strong.
This principle also applies to other major cryptocurrencies that implement deflationary mechanisms, such as Ethereum’s fee-burning model introduced after the Merge.
How to Buy Cryptocurrency Easily and Securely
Getting started with cryptocurrency investment doesn’t have to be complicated. You can begin by purchasing major digital assets like Bitcoin (BTC), Ethereum (ETH), Tether (USDT), and Litecoin (LTC) using familiar payment methods.
Platforms like OKX allow users to buy crypto directly with a credit card or Apple Pay, making entry into the market fast and accessible—even for beginners.
To get started:

- Complete SMS verification.
- Navigate to the “Buy Crypto” section.
- Choose your preferred payment method and select the cryptocurrency you want.

Earn Passive Income Through Flexible Crypto Yield Opportunities
Holding cryptocurrency doesn’t have to be passive. Many investors boost returns by participating in activities like staking, liquidity mining, or yield-generating products.
However, traditional staking often comes with complex rules, high entry barriers, and network fees that eat into profits.
OKX simplifies this process by offering flexible, low-cost earning opportunities across a wide range of major cryptocurrencies—with no network fees required. These products are designed for both new and experienced users who want to grow their holdings without technical complexity.
From fixed-term savings to flexible deposits, there are options tailored to different risk appetites and financial goals. Simply head to the “Earn” page to explore available plans and start generating passive income on your crypto assets.
Security First: Protecting Your Digital Assets
In the decentralized world of cryptocurrency, security is non-negotiable. OKX prioritizes user protection through a multi-layered security architecture designed to safeguard funds against theft and unauthorized access.
Cold Wallet Storage & Advanced Encryption
The vast majority of user assets are stored in offline cold wallets, completely isolated from the internet. This drastically reduces exposure to hacking attempts and online threats.
Both cold and hot wallets are protected using cutting-edge encryption protocols, ensuring that even if systems were compromised, attackers couldn’t access private keys or user data.
Multi-Factor Authentication Tools
Beyond platform-level security, OKX empowers users with powerful tools to secure their own accounts:
- Two-factor authentication (2FA)
- SMS verification
- Google Authenticator integration
These layers make it significantly harder for malicious actors to gain control of an account—even if they obtain login credentials.
Regular security audits, withdrawal whitelisting, and anti-phishing code features further enhance account safety.
