Unlike conventional coinage-prone currencies, the cryptographic rules applied to bitcoin make their owners avoid the same risks.
Bitcoin payments are fully encrypted / cryptographic, so personal info is safe and unobservable to others. What other people can see is only the address used for the transfer only. You are also protected from identity theft cases that rampant in ordinary banking.
Because wherever we are in this world, no need to bring cash we can buy or pay it by the used of Bitcoin that's why we can say that Bitcoin is very safe.
