Not all crypto-currencies are anonymous. Already a lot of users have learned to track someone else's transactions bitcoin. So what prevents hackers from tracking down information and hacking a wallet?
I do not argue with this. Usual money is protected. Crypto currency - the ideal environment for hacking and theft. There are no mechanisms of legal protection, only the preventive measures of the users themselves.
If you show care and ingenuity, then you can use the crypto currency to save yourself a deposit for a Swiss bank. But for this you need to securely protect your PC.
