No.
Unlike many exchange services, all of our fees are clear and upfront. We do not charge you above market value for Bitcoin purchased, and we do not keep a spread of the difference. We use our backend execution engine to give you the best price available to us.
Your Bitcoin is exchanged for USD within your own custodial Prime Trust account and is sourced from a variety of exchanges and OTC desks. They buy the Bitcoin for you at the exact time you request it. Price can fluctuate across exchanges and desks by fractions of a percent.
How can I verify the timestamps and prices of my purchases?
Please use the CSV download available in your dashboard below the purchase area, or in your settings page. This file will contain the UTC timestamps of every buy, which you can verify against other exchanges.
