The price of e-money and tracking software has become a target of cybercrime, but it also opens up a new market for cybersecurity.
Stealing e-money seems to be becoming a profitable industry with annual revenues up to $ 200 million, that hackers infiltrated more than 14 percent of the global bitcoin and ethereal supply.
Source or gtfo of here. First of all, we do not call this e-money, because it is a Crypto currency. Now Bitcoin being a currency <like fiat & credit cards> and having value, would make it a target for hackers. The Bitcoin software or protocol has never been hacked, but the services around it, where they make use of their own software, has been hacked before. <Exchanges / Wallet providers etc.>
Bitcoin <The technology> cannot write the software for all these companies, so they are not responsible for the security of these services.
What is Ethereal?
..... You should really do more research. <Ethereum>
