It's very easy and safe to buy many things around the world.
it's very fast to move or transfer money to anyone and the fee is too low.
I think that you saying "safe to buy" is not safe at all, why? because there are many sellers that using bitcoin as a payment to scam other people, it will be safe if you will hire a trusted and reputable middle man, also if you're buying items on the internet using your bitcoin do research first about the website before you pay the items.
