Entering the world of cryptocurrencies can seem intimidating for beginners. Technical terms, different types of wallets, risks, and opportunities arise all the time. But the good news is that, with the right tools and some basic precautions, it is entirely possible to take the first steps in the crypto market safely.
To make this detailed path easier, we created a guide. This guide was designed for those starting from scratch or wanting to better structure their first investments. Let’s go through the step by step!
1. Choose a reliable exchange
The first step for those who want to buy and sell cryptocurrencies is to open an account at an exchange (crypto broker). Choose platforms recognized in the market, with a good reputation, a history of security, and that offer support in Portuguese.
Exchanges like Binance (among other major global brokers) are examples of platforms that usually offer a good experience for beginners. Also, analyze whether the company is registered with regulatory bodies and if it complies with good compliance practices.
Research what people are saying about the exchange, check Reclame Aqui, and when choosing the broker, see what communication channels are available with them in case of need.
2. Identity verification (KYC)
When opening your account, the exchange will ask you to go through an identity verification process known as KYC (Know Your Customer). This involves sending documents such as ID or driver's license and, in some cases, a selfie.
This step is mandatory at most serious brokers and helps prevent fraud, money laundering, and other financial crimes. In addition, it allows you to access higher operation limits.
Not having a step like this should serve as a warning sign: if the exchange does not check the data of those opening accounts, how can you know if it will take care of the resources you put there?
3. Activate two-factor authentication (2FA)
After creating your account, one of the first settings you should make is to activate two-factor authentication. This is an extra layer of security that requires, in addition to your password, a temporary code generated by an app (like Google Authenticator or Authy) to access your account.
2FA protects your account even if your password is compromised. It is never advisable to keep this feature disabled, as it can prevent you from having problems such as a hacking that could take everything you have saved/invested until then.
4. Understand the difference between hot and cold wallets
When you buy cryptocurrencies, they are stored in a digital wallet. There are two main types:
Hot wallets: are connected to the internet, like those that exist within the exchange itself. They are convenient for those who make frequent transactions but more vulnerable to hacker attacks;
Cold wallets: are physical devices (like USB drives) that store private keys offline. They are ideal for those who want to keep crypto assets for the long term, with more security.
For those starting out, leaving assets on the exchange itself may be sufficient, but as the amount invested increases, it is important to consider safer alternatives. Therefore, even if you do not implement everything you learn while researching this right away, it is good to stay informed about the best options regarding this topic.
5. Manage your risks from the beginning
The crypto market is known for its volatility. Therefore, it is essential to adopt good risk management. Here are some important practices:
Do not invest more than you can afford to lose;
Start with small amounts to understand how the market works;
Diversify among different assets;
Have an entry and exit plan for each investment.
This is one of the most fundamental steps of the entire guide. Generally, people start thinking about investment risks only when they experience a significant loss, but by starting with proper management from the outset, you will go through much less trouble.
6. Study before investing (DYOR)
In the crypto world, one of the most famous rules is: "Do Your Own Research" (DYOR). Before buying any cryptocurrency, research:
What problem does the project solve?
Who is behind the initiative?
What is the market capitalization?
Does the project have a transparent and up-to-date whitepaper?
Avoid following recommendations from influencers or social media groups without first understanding what you are doing. Learning about a crypto project this way is one thing, but putting your money into it is another; it requires much more responsibility and analysis.
After all, don’t forget: if that influencer or social media group is being paid to tell you about some 'great opportunity', the one who will lose money is only you.
7. Consider using the DCA (Dollar Cost Averaging) strategy
One of the simplest and most effective ways to start investing is by using DCA. With this strategy, you invest a fixed amount periodically (for example, every week or every month), regardless of the price of the cryptocurrency at that moment.
Over time, this smooths the average entry price and prevents you from buying everything at a time of high. In addition, it reduces the emotional impact of market fluctuations.
In fact, an easter egg tip: this is the best strategy to buy foreign currency before traveling abroad. There is no 'ideal moment', but there is risk dilution if you always buy a little every period.
8. Be careful with promises of easy profit
Scams are common in the crypto sector, especially among beginners. If someone promises guaranteed returns, quick profits, or asks you to send crypto assets in exchange for future promises, be suspicious. The market is dynamic, but it is not magical.
Again, it is worth remembering step 5, about managing risk: you are free to make whatever decisions you want, but you will be bound by the set of consequences of those decisions. This applies to life as well as to markets. Knowing what you are doing - and what risk you are taking - is essential.
9. Stay updated
The crypto ecosystem evolves rapidly. New technologies, regulations, wallets, and projects emerge all the time. Therefore, keep up with the news, participate in trusted communities, and be willing to learn constantly.
Sites like Binance Academy, Square, Blog, among others, offer free and accessible content for those who want to stay informed.
If you have a profile more focused on trading (quick operations) and not just HODL (buy and 'forget', waiting for future appreciation), there are also signal groups on Telegram that discuss more specific points and short-term opportunities.
So, when are you going to start?
Starting to invest in cryptocurrencies in 2025 is more accessible than ever, but it also requires responsibility. With information, security, and discipline, it is possible to seize opportunities in this expanding market.
Choose a good exchange, keep your account secure, understand where you are investing, and proceed consistently. The crypto market has enormous potential, but your preparation will make the difference in the long run. In summary: follow this guide to avoid trouble in the crypto universe.
If you’ve made it this far, you are already one step ahead of most. Now just follow calmly, with focus and security!
