You are on Bitcoin forum and you ask about safe form of payment?

Haha! That was funny.
One of the main advantages of Bitcoin and many other cryptocurrency payments is that are non-reversable. Usually, several network confirmations are required to be sure. However, you are sure that such threats that you may encounter on the services listed by themos will never meet you with Bitcoin.
Yes, I understand about that. I am just needing to buy bitcoin with fiat, and I prefer to buy peer-2-peer than through an exchange. Unfortunately I only have PayPal or CC right now, but I'm more than willing to shift money around to use another service or payment processor, if I knew which one.
