HOT WALLET it’s a type of Wallet Accounts ALWAYS CONNECTED ONLINE.
sample, Coinbase and wallet accounts in Exchanger sample Poloneix, Bittrex, BTC-ALPHA, Binance etc.
how much secured are you using HOT WALLETS? HOT WALLETS depend on the security of an Account that they have him with security features or security option if there is a set up of google auth or any authenticator is more secured or has a hidden question, seed.
the only tip here is to keep a big ammount on hot wallets because it’s still a type of wallets.
and COLD WALLETS. I just sample it HARDWARE WALLETS. These are wallets that are touching. or offline wallets Like TREZOR.IO at LEDGER NANO.
How much secures are you using COLD WALLETS? because it’s stored OFFLINE and is handled by HARDWARE WALLETS it does not block any HACKER. And they have him with security features. The only weakness of these Hardware Wallet is to misplace it so we keep the Hardware Wallets.
what else do you think you can add to this information?
