What is the cost to buy or sell cryptocurrencies? Gemini is another well-respected cryptocurrency exchange. Gemini is a trust company that operates as a fiduciary, meaning that it must meet compliance, capitalization, anti-money laundering, cybersecurity, and consumer protection standards set forth by the New York State Department of Financial Services NYSDF. So far, the company has had a good record of security and grown internationally to allow users in over 25 countries to buy and sell cryptocurrencies and provide cryptocurrency wallets to users in countries. Regardless, Gemini does claim to be insured by a top tier insurance company to protect you from internal malfeasance. This considerably decreases the likelihood of an account being phished or hacked. The response times for these services seem to be quite similar to issues being replied to within a couple of hours to around 24 hours.
