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.
Cryptocurrencies are open, anyone can find out how much money in on the wallet in the Ethereum, so these wallets are the most hacked. It is easy to track all bitcoin accounts by IP and link them to a one wallet.
The security of cryptocurrency wallets is a very big problem. There are a lot of cryptocurrency wallets, but a few a safe one. But even the most secure wallet can become dangerous if the computer is infected by the viruses.
