It is much safer for me to buy things on the Internet with cryptocurrencies than credit cards. It seems like every few months there's a huge leak of customers and credit card information.
I'm a fan of bitcoin, but in this case I disagree. It is safer to sell things on the internet if you accept bitcoin, but it's more risky if you're the buyer. You can chargeback a credit card if you don't get what you paid for. You can't get your bitcoin back.
