Hi ..we all know that are wallet is not safe as what we expect as safebox..but just anyone know what is the safest wallet here in internet..?
The safest wallet is one that you control the private key to, and that is not connected to the internet. This is called a cold wallet. There are a few different ways that you can run a cold wallet.
My preferred choice is using a hardware wallet, such as a Keepkey or Trezor, which can hold the private keys to a nearly unlimited number of public addresses. Those private keys never leave the hardware wallet, which is protected by a PIN. This allows you to complete transactions or sign messages without ever actually releasing your private keys from the hardware device.
You can also use a paper wallet, in which you simply write down the private key to a public address on a piece of paper and keep that paper safe, but I’ve never done this.
If you absolutely must use an internet-connected wallet (a hot wallet), then using multisig security is a major benefit. Basically you would distribute authorization among several devices, and require a certain number of those devices to sign off on any send transaction.
Obviously if you use any internet service to host your wallet (such a Coinbase or Bitpay), make sure that your account password is 40+ randomized letters, numbers, and symbols, and set up 2-factor authentication.
Good luck!
