Stay safe — security basics
Seed phrases, 2FA, phishing, hardware wallets — rules that prevent 99% of losses.
Most people don't lose crypto to price drops — they lose it to their own mistakes or to scammers. Security in crypto isn't optional, it's the absolute basics. These few rules protect your money better than any antivirus.
4 pillars of crypto security
1Seed phrase — guard it like your life
12 or 24 words that give full access to your wallet. Write them on paper (NOT on phone, NOT in cloud, NOT in email). Whoever has the seed phrase has your crypto. End of story.
22FA — always, everywhere, mandatory
Enable two-factor on every exchange and app. Use Google Authenticator or Authy — never SMS (SIM-swapping is a real threat).
3Phishing — don't click, don't trust, verify
Scammers impersonate Binance, MetaMask, Coinbase — emails look identical. Rule: never open an exchange via an email link. Always type the address manually or use a bookmark.
4Hardware wallet — for serious amounts
Ledger or Trezor is a physical device that stores your keys offline. No hacker can reach a wallet that isn't connected to the internet.
🚩 Red flags — run away when you see:
- “Send 1 ETH, get 2 ETH back”
- Someone on Telegram offering you a “guaranteed profit”
- A site asking for your seed phrase or password
Transfers — the “check 3 times” rule
There is no “undo” button in crypto. Send funds to the wrong address or via the wrong network and they're gone forever. Here's how to do it safely:
1Always do a test transfer first
Sending a larger amount? First send the absolute minimum (e.g. $2–5 worth). Only once you see the funds arrive in the destination wallet, send the rest. Costs you a few cents extra in fees — buys you peace of mind.
2Verify the network
The most common newbie mistake. If you send USDT over Ethereum (ERC-20), the receiving address must support ERC-20 too. Picking the wrong network (e.g. sending from Solana to an Ethereum address) is the easiest way to lose your money.
3Copy-Paste + double-check
Never type an address by hand. Always use the “Copy” button. After pasting, verify the first 5 and last 5 characters of the address. Clipboard-hijacker malware exists — it swaps your copied address for the attacker's at the moment of paste.
4Don't rush
Doing transfers in stress or in a hurry is asking for trouble. Sit down, double-check, take a breath, and only then click “Send”.
