14% of all stocks of bitcoin and ether are earned by criminal means
Employees of the analytical company Autonomous Research conducted a study in which they found out that over the years since the appearance of the crypto-currency years, hackers were able to steal more than $ 1.2 billion in bitcoin and ether equivalent. At the same time, researchers say, at the end of 2017 the amount was even more impressive.
It seems that theft of the crypto currency is a very profitable occupation, because in a year it brings criminals about 200 million dollars. In addition, more than 14 percent of all stocks Bitcoin and Ether are currently earned dishonestly.
Many people consider the blockade to be super-secure, but in fact in many respects it is almost as vulnerable as other software. The market of crypto-currency is now quite immature, there are a lot of block diagrams, and each of them has its own mistakes, and the more of them, the more difficult it is to cover them all, study and secure them, "explains Matt Sueche from Comae Technologies, which deals with blocking security.
Crypto-security specialists are sure that the market for software, services and hardware solutions for the protection of the blockboys will continue to grow actively. So, last year its volume was estimated at 259 million dollars. In 2018, growth is expected to reach 355 billion.
The protocal itself is extremely secure. What the blockchain says goes as far as wallet ballance for every single wallet on the ledge are concerned.
As far as your password or wallet.dat file that is your key to your specific wallet, that is as secure as anyones passwords are. Your funds are as secure as your password. The major difference between blockchain digital currencies and traditional currencies is that you dont need to have your password stored somewhere digitally. With banks it is stored on their side of the database or on your computer which is subject to hacks and data breaches. With blockchain you can store your password on a piece of paper off the computer as a "cold wallet" and access the wallet only when you need to. So unless they steal your piece of paper that holds the key they wont get in because there is no breaching the blockchain protocols side that validates your password.
Of course this is less convenient, most often convenience is the cost of more security.
