A week ago, I read about the safest wallets, I found out that the safest are paper wallet and hardware wallet. The wallets are offline but to make a transaction, you have to connect it online. I later read of a malware that can steal cryptocurrencies from trezor or ledger nano in just 15 seconds which are the best hardware wallets.
So, we need to know how to manage our wallets too and have a strong antivirus to protect us from hackers and also we need to know the latest threats from cyber criminals so that we can protect ourselves away from them.
Virus can't infected our Computers if we don't click malicious link and other unknown applications (don't download). And also always check our pc link clicking virus scan before connecting our hardware wallet to make transactions. And your right! We need to keek updated always in other ways of hackers to victim us. So that we will be safe always here in crypto currency world.
