Which country do you live in? Most of the exchangers don’t accept credit card nor Paypal due to fear of chargeback.
But there are some sites depending on your country. But you will surely have to undergo ID verification if not you will have to pay huge amount of fee for buying. Like virvox charges around 20-25% for Paypal.
You can also look into cex.io. They allow credit card payment after ID verification.
