By making a successful purchase of crypto, your card details are automatically saved so you can select that card for future transactions. There is no limit as to how many cards you add to your account. Note: The total crypto rewards paid are limited up to $100,000 in exchange volume per month. That means you’ll get rewarded until your total monthly amount of swaps reaches $100,000. That limit resets back the description to $0 on the 1st day of each month. Fantom is also an inflationary token, meaning that the total number of FTM tokens will increase over time, but only up until a point – the token’s supply is fixed at 3.175 billion. Once all of the tokens have been issued, which crypto data platform Messari predicts will occur in 2024, no more FTM tokens will be introduced into circulation.
