Cryptocurrency transactions are irreversible. If you send cryptocurrency to a third party, you cannot reverse it or stop payment. When you send cryptocurrency to a blockchain address, you must be certain of the legitimacy of any involved third-party services and merchants, and only send cryptocurrency to entities you trust.
Pro tip: If it sounds too good to be true, it probably is.
Employment scams
Scammers will impersonate recruiters with fake job offers, actively seeking job hunters to steal cryptocurrency and personal information. Most frequently, the scammers will reach out to individuals who have posted their resumes online, and ask for payment to begin training. These "job offers" often include convincing offer letters and they may ask for confidential personal information.
All legitimate job postings will be posted on www.coinbase.com/careers. No other URL should be trusted for job listings.
All legitimate communications with Coinbase recruiters will come from @coinbase.com email addresses.
