I never lost any single Bitcoin nor altcoins. I quite few times heard and read that some people were complaining or remaining without funds from wallets. There should be taken some extra steps when you are willing to store your coins locally. A good antivirus with encrypted wallet is good way of protecting like me.
Really? This is the first time that seeing someone and saying that he never lost bitcoin or alt coins. Is that for real? I can't really believe that there are few people like you. Maybe you are just lucky that you haven't victimized by those hyip's or cloud mining scams because most of the people here lost their bitcoins because of it.
