I am confused on how cold wallets and hot wallets differ. To make any transaction we still need to get access to internet. Then how are they different?
Being connected to the internet makes the wallet hot and every wallet needs to connect to the internet for any transactions.
The safest way to keep bitcoins safe is to store them on Hardware WALLET.A wallet that is specifically built to hold cryptocurrency and keep it secure. This includes USB devices. These devices can go online to make transactions and get data and then can be taken offline for transportation and security.You can trust it because proven and tested.
