Thank you for this warning. Nothing is safe nowdays, DDOS attacks, hackers and malwares have become usual part of everyday living. Is there any secure way to protect ourselves form this? Are service providers doing enough in their measures for security of their users and their servieces? The very bad thing is also that some of this attacks are actualy sponsored of certain governements like is that often case with russian hackers who have their special aimes.
Protecting ourselves couldn't be easier . We simply shouldn't trust centralized exchange or in other words , exchanges that doesn't give us control over our private keys , I'm not saying that exchanges shouldn't be used but people shouldn't store their coins for long term there , once you trade , withdraw your funds. Poloniex is the most secure If you ask me as they are storing their funds in cold storage means no hacker will have access to them and If the website gets hacked the losses are going to be limited.
