Crypto credit cards are a HUGE SCAM, don't do it.
Here's why.
So, you have your XRP with your "card provider".
They give you a credit card, r.g. MasterCard.
You go and spend $100 on it.
Your card provider sells your XRP (OH, BY THE WAY, MUCH CHEAPER THAN REAL MARKET VALUE), and pocket the spread.
They also get kick back from MasterCard for the transaction..
Does that sound like a good deal? NO.
Just get a debit/credit card from a bank (you get rewards too), spend on it.
And when the XRP price looks good, within your 30 day billing cycle, pay your fkn card off.
Simples.
