🔐 #CryptoSecurity101 – The 5 Mistakes That Cost You Everything (and How to Avoid Them)
In the crypto world, you don't need sophisticated hackers to lose everything: often, human distractions are enough. Weak passwords, wrong clicks, unprotected wallets: most crypto thefts occur due to user error.
In this guide, I show you the 5 most common mistakes and how to avoid them if you really want to protect your digital capital.
⚠️ 1. Using the same address on multiple platforms
Every time you reuse the same public wallet (e.g., to receive payments or airdrops), you are making your entire financial history visible to anyone.
✔ Solution: use different wallets for trading, airdrops, DeFi, and cold storage.
🔑 2. Write the seed phrase on Google Drive
It seems convenient... until someone hacks your email.
Never save private keys in the cloud or on apps connected to the internet.
✔ Solution: Write the seed phrase on paper, even better on metal, and keep it offline in two separate locations.
🧩 3. Signing transactions blindly
Some DeFi attacks rely on malicious smart contracts. By approving without checking, you grant unlimited access to your wallet.
✔ Solution: use tools like Revoke.cash to monitor permissions and sign only if you understand the contract.
📲 4. Not using two-factor authentication (2FA)
SIM swap attacks or email phishing are still the preferred methods for stealing crypto accounts.
✔ Solution: Activate 2FA with apps like Authy or Google Authenticator, never via SMS.
🧠 5. Trusting links and bots that are 'too good to be true'
If you receive an unexpected airdrop, or a bot messages you on Telegram with outrageous promises, it is almost always a scam.
✔ Solution: Avoid FOMO. Don't connect your wallet unless you are 100% sure of its authenticity.
🛡 Bonus: perfect security does not exist, but ignorance is the real enemy
Even the best trader or holder can fall into a trap if they do not update their mental and digital defenses.
🔐 In crypto, you are the bank. And if you make a mistake... there is no customer service.
