I think the difference in real money and bitcoin is the ease, security and speed. bitcoin better everything rather than real money so that users of the bitcoin on the rise.
Safety and speed now is more suitable just for real money. Because there is a possibility that bitcoin wallet can crack, and the speed of operations is too long.
Yeah there is possibility for bitcoin wallets to be cracked but there is a lot of wallets to choose from like the hardware wallet which is virus and malware proof. You can easily buy a few of them to try what is the best for you and for sure your gonna love the hardware wallets because of the high security, but as other says, it is still up to the owner of the wallet if he will have a very careful management for his wallet or not.
