Perguntas Frequentes

Qual a carteira mais segura para criptomoedas?

Hardware wallets (Ledger Nano X/S Plus, Trezor Safe 3/5) são o padrão ouro para custódia própria de longo prazo. Mantêm chaves offline e assinam transações fisicamente.

O que é seed phrase e como proteger?

Sequência de 12-24 palavras que regenera sua carteira. Nunca digite em sites, nunca fotografe, nunca guarde na nuvem. Grave em metal (Cryptosteel, Billfodl) e guarde em local físico seguro (cofre, esconderijo).

Como evitar golpes em cripto?

Nunca clique links suspeitos. Verifique URLs (phishing usa domínios parecidos). Desconfie de "garantia de retorno", "airdrop grátis conecte carteira", suporte falso no Telegram/Discord. Use 2FA (authenticator app, não SMS).
