I am very interested to know if cryptocurrency wallets like Bitcoin Core, NEON, Electrum can ever be hacked ?
Anything can be hacked, if you are not careful. Pay great attention to bolstering your online security. Also, be mindful of the information you are sharing with others to prevent getting hacked.
I really agree with this, we don't underestimate the network security and hardware that we use when opening a wallet, keep your wallet safe like you take care of yourself...
