Yes, the bitcoin is a very safe method for payments, plus its also fast.
The only thing you need is a secured wallet, use blockchain or something.
Preserving your bitcoin is safe but if you want to ensure what you have has price, I mean ensure from not decreasing value then bitcoin has some risks.
Indeed, very good aspect of the question.
Bitcoins are safe, you're not going to get ripped of your btc. But btc might still lose a lot or all its value, and nothing protects you from that that's right!
