One of the best ways to determine if your exchange or wallet provider is legitimate is to research the company. Read customer reviews and be wary of claims that seem too good to be true. Check the website for spelling and grammatical errors, including the domain name. Also check that the company offers customer support and security features, like 2FA. You want a company that values you as a customer, including your safety and protection. Finally, make sure the company has a real, physical address with contact information. You don’t want a provider that is hiding their identity or location.
