Some merchants along with Crypto.com will preauthorize an amount that is higher than the actual purchase amount especially:

These merchants may estimate its final value and place a temporary hold on your Crypto.com Card’s funds for the amount indicated by the merchant. The available balance on your Crypto.com Card will need to be sufficient to cover this amount otherwise may result in being declined.

Until the transaction finally settles, the funds subject to the hold will not be available to you for other purposes. Note that Crypto.com may also preauthorize a higher amount for these services. We will release any excess amount when the transaction finally settles.

Some gas stations may factor in additional amounts to cover the potential filling of the tank, which can be around $50-150. To avoid such a hold, you may want to pay at the register inside the gas station, instead of paying at the pump.

Generally, these merchants place a hold that is greater than the actual charge to allow for any extra incidental charges. It may take up to 60 days after your stay or your rental to have any excess amounts held by the hotel or rental company added back to your available balance.

Certain restaurants & service-oriented merchants may hold an amount that is slightly larger than the bill in the event that you include gratuity on your Crypto.com Card transaction. Accordingly, you should ensure that your available balance is 20% (or more) greater than your total bill before using your Crypto.com Card.

There are no administrative charges for overseas withdrawal of cash if I keep within the cash limit of the card.

All the card Limits (e.g. free ATM withdrawal, interbank exchange rate, top-up, or ATM withdrawal) and Fees can be found in the Settings, in the Fees & Limits section. There are differences between the fees and limits depending on your card’s tier (lowest limits for Midnight Blue and highest for the Obsidian), so be sure you’re checking the correct card tier.
