If you were going to do this, what card would you use?
Do any credit card companies have restrictions on bitcoin purchases?
Which cards offer incentives and bonus dollars for purchases?
I will definitely use Paypal and Visa card. Because it is one of the reputable businesses and they serve a lot of customers, they will definitely sell and buy at very reasonable prices.
I am waiting for them to launch crypto buying and selling services, I will save much more money and time in trading between fiat money and crypto.
If you are having money in paypal then you can actually trade it for fiat even now by using curreny exchange but it is not OP asking.
Will you make investment on crypto currency using credit car means the lend money which has high risk.
