There are a few simple rules that ensure your coins’ security:
- Never share your BTC private key with anyone under any circumstances. No one is entitled to require it from you.
- Check and double-check every transaction. There is no way to get your coins back if you made a mistake, as transactions in blockchain are irreversible.
- Don’t publicly boast of your crypto holdings. This includes online boasting under your real name or identifiable and\or trackable pseudonyms.
- Create a separate email for your Bitcoin wallet and don’t use it for anything else.
- Enable Two-Factor Authentication (2FA) for your wallet to ensure its security.
Also you can buy Bitcoin both with USD, EUR, NZD, GBP, CAD, AUD circulating in English-speaking countries, and with other currencies
