Beginner's guide to crypto
Cryptocurrency represents a new era of money — decentralized, transparent, and accessible to everyone. This guide explains what crypto is, how it works, its main types, and what risks to be aware of before getting started.

Cryptocurrency is changing how we think about money. For a long time, people could not imagine a form of money that wasn’t tied to banks, banking hours, processing time, and fees. With crypto, however, we can begin to utilize a system that enables us to send funds across the world within minutes, using nothing more than a device that is connected to the internet.
So what is this revolutionary vision of money, and how does it work?
Cryptocurrency is a form of digital currency that uses cryptography (a method of protecting information by using codes) to securely operate on decentralized networks, known as blockchains, that are not controlled by a single bank or authority.
A blockchain is a digital ledger that records transactions. The way it works is by storing transaction information in the form of “blocks” that are tied together, forming a “chain”. Hence the name: blockchain.
Through the blockchain, any user has the ability to verify data. The nature of blockchain is that it is public and transparent, showing all transactions. This ensures security and gives traders the confidence that their transactions will not be tampered with.
The vision of crypto is to be accessible to everyone anywhere, and to give its users complete ownership of their funds without relying on banking institutions. This is supported by crypto’s key features: decentralization, transparency, and security.
Types of cryptocurrency
Not all cryptocurrencies are the same. There are different types, each serving a different purpose. Here are the main ones:
Bitcoin (BTC): the very first and most well-known cryptocurrency, often referred to as “digital gold.” Bitcoin was created in 2009 by an anonymous person or group known as Satoshi Nakamoto. Bitcoin has a fixed supply cap at 21 million BTC, and currently has a market cap around $2.27 trillion USD.
Altcoins: this refers to all other cryptocurrencies besides Bitcoin. This includes Ethereum, Solana, Litecoin, and many more which you can explore in our Market page.
Stablecoins: this is a group of cryptocurrencies that are designed to have their price matched with traditional currencies such as the US dollar, in an attempt to reduce their price volatility. Examples of stablecoins are USDT and USDC.
There are many other types of cryptocurrencies, such as utility tokens, security tokens, and memecoins. Each of these provide a unique use and purpose.
How is crypto used today?
There are many ways in which crypto can be used today, and some of the most common uses are:
Trading and investing: platforms like Rain provide interested traders with the chance to buy, sell, and store crypto. Many traders keep an eye on price movements to determine when to buy, sell, or continue to store in order to gain profit.
Payments: some businesses around the world started to accept crypto as a form of payment for goods and services, and many people have taken advantage of this to access a range of goods and services, from video games to real estate.
Transfers: a very crucial aspect of crypto is how it is borderless, therefore making international money transfers possible in a much faster and cost effective way across continents.
In addition to the above, blockchain offers multiple ways for traders to use and grow their crypto holdings. Examples include access to DeFi (allowing you to lend, borrow, or trade crypto without banks), NFTs (unique digital collectibles like art or music), and more.
Risks to consider
Just like any form of investment, investing in and trading crypto has its risks that everyone should keep in mind.
One of the most obvious risks of crypto is its volatile nature. Crypto prices tend to move rapidly, which means they can rise and fall within minutes. Traders must consider this to avoid unexpected losses.
Due to the nature of blockchain, another risk that trading crypto poses is that transactions are irreversible. Once a transaction is done, it cannot be undone or changed. For example, if you make a mistake in the wallet address, the sent funds will be lost.
Another risk comes from scams and fraud attempts, which are usually in the form of fake projects or phishing attempts. As always, make sure to check sources before taking any action. You can read this guide we prepared for you to learn more about how to detect and avoid scams.
