More and more people are looking to invest in cryptocurrencies as a result of bitcoin’s recent price surge, but by doing so they could become prime targets for cyber criminals.

Something as simple as a USB or an external hard drive can be used as a “cold” wallet.
“The safest way for users to store their bitcoin is to use offline wallets which are not connected to a computer,” Symantec threat researcher Candid Wüest…
