It's good. I think it's a good upgrade but I have a few suggestions here:
I would like to point out that when the following page for example:
https://www.coinsbee.com/en/gift-cards/payment-cards/my-prepaid-center-mastercard/You would expect that clicking one of the payment methods on the left side, would actually take you to the payment page directly but it doesn't, it just takes you to a page where it tells you that you can pay with Monero (or whatever coin you have selected).
I think the behavior should be: It should either redirect you to the payment page, or shouldn't be clickable at all so we know it's only "for display" and so that the user has an idea what payment methods he could later use after adding the gift cards to his cart.
I also don't see the point of selecting "the estimated price". It just gives the impression that I'm selecting the payment method.. but then in the payment page, I'm asked to select the payment method, again.
