Perhaps the most compelling reason to use cryptocurrency-linked plastic cards is the ability to have easy and constant access to your funds and to use them quickly in case of an abrupt need.
For example, if you are traveling and your regular bank card has been blocked or stolen and you need to pay for something urgently and do not have the time or ability to change cryptocurrency in other ways, you can safely take a coin card out of your pocket and make a payment.
But if we are talking about everyday use of bitcoin wallet-linked cards and we are talking about a card whose account can only be credited with bitcoins, then the benefit of this option is very doubtful.
You will have to change bitcoins according to the exchange rate at the moment of transaction, and it may be far from the most profitable rate on the market (for example, internal service rate).
Normal Bitcoin exchange rate fluctuations can make a transaction quite unprofitable. It is much easier to wait for a good rate, exchange bitcoins on the exchange and withdraw them to one of the payment systems or a bank account.
In addition, cryptocurrency card services use additional fees for their clients' transactions.
However, in order to be comfortable using digital cards for payments you should turn to the trusted financial platforms such as https://askwallet.io/rebelion.
