Bitcoin with your credit card is just as simple as buying with a debit card or paying directly from your bank account, though it does come with a few extra restrictions. Another concern is that credit card companies will have more fraud losses as a result of customers using them for bitcoin purchases.
The fraud losses are there to insure that you can have a fight when things go south with your finances, I personally like the concept that we can use credit card to transact with bitcoin and other cryptocurrencies. Credit card in my opinion is a good thing if used wisely because there are perks that you can get just by applying for it and it can help with your credit score, remember that it is the holder's fault that they are in debt with credit card. Do not be discourage when people say things about credit card, they might have a bad experience but that does not mean that it will be the same experience for you.
