🔐 Security in Cryptocurrencies: The Basics That Every User Should Know
The crypto ecosystem offers freedom, decentralization, and autonomy. But with that also comes great responsibility: to protect your digital assets. Unlike a bank, if you lose your funds due to a scam or poor security practices, there is no possible reimbursement.
In this article, I share the fundamental pillars for you to operate more securely in the crypto world, regardless of whether you are a beginner or an intermediate user.

1. 🔑 Never share your private key or seed phrase
This is the most important thing. The seed phrase (the 12 or 24 words) or the private key gives you full access to your wallet. If someone gets it, they can empty your wallet in seconds.
DO NOT store it in photos, emails, or notes on your phone.
Use paper and pen, and store it in a safe place, preferably duplicated.

2. 👁️🗨️ Always verify the sites you visit
Phishing is one of the most common scams. Attackers create fake sites that mimic platforms like Binance or Metamask.
✅ Tip:
Write the URL yourself or use secure favorites.
Enable two-step verification (2FA), preferably with apps like Authy or Google Authenticator (not SMS).

3. 🧊 Use cold wallets if you are going to hold long term
Hardware wallets (like Ledger or Trezor) store your cryptos offline, making them much more secure against hackers.
Ideal if:
You will store for months/years.
You don't need to move funds daily.

4. 🧠 Beware of promises of easy returns
If something sounds too good to be true... it probably is.
Common scams:
"Investments" with extremely high fixed returns.
Apps or smart contracts that request full permissions (approve + transfer).
NFTs that require connecting your wallet to unknown sites.
Always research the project, the community, the contracts, and who backs it.

5. 🧾 Keep your devices and systems updated
Security updates on your browser, phone, and wallet apps are key. Do not use outdated versions or unsupported operating systems.
