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.
I don't understand what you ask, but I know, that there are several types of wallets. for example, wallet online with an offline wallet.
if we talk about security, offline wallet is the choice, it doesn't mean that online wallet is not safe, but to safer offline wallets.
