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.
Technical Support and Impersonation Scams
Fraudsters set up scam customer support phone lines and impersonate a variety of companies—including Coinbase—in the finance, tech, retail, telecom, and service industries. These scam phone numbers are spammed on the internet, luring unsuspecting victims seeking assistance. The scammers may also conduct outbound calls directly to potential victims. These scammers are skilled in social engineering, making false claims to deceive and manipulate their target into providing personal information that will be used for fraudulent purposes.
Never give support staff (or anyone else for that matter) remote access to your machine. This effectively gives the scammer full access to your computer, online financial accounts, and digital life
Never give out your 2FA (2-Factor Authentication) security codes or passwords. Coinbase staff will never ask you to share sensitive authentication credentials
Never accept outbound calls asking for your confidential personal information. Be aware that scammers can spoof legitimate phone numbers when conducting outbound calls
- Never send cryptocurrency to external addresses on behalf of alleged support agents. Coinbase staff will never ask you to send cryptocurrency to external addresses
Scammers are using social media to perpetuate giveaway scams. They post screenshots of forged messages from companies and executives promoting a giveaway with hyperlinks to fraudulent websites.

Loader or Load-up Scams
Fraudsters frequently offer “loading” services on a variety of platforms. They claim to need Coinbase accounts with high limits, offering the victim a portion of the proceeds. These scammers use stolen credit cards on compromised accounts to perpetuate payment fraud. The end result is the victim is left with payment delinquencies after the legitimate card holder discovers the fraud, the scammer often steals any available cryptocurrencies and submits unauthorized charges on verified payment methods. Be aware, you are responsible for any payments submitted using your authentication credentials.
Never provide your passwords or security codes to third parties under any circumstances
