A round of phishing emails went out targeting Stellar users. The Stellar Development Foundation does not offer a staking service. We are not holding a staking competition. If you receive an email say so, it's a phishing attempt. Always check who the sender is if you receive an email from SDF. If it's not from an email ending in http://stellar.org then SDF didn't send it. Don't give anyone your secret key or seed phrase. If you are entering your secret key into a website, always doublecheck the URL.
