At any time, if the amount of money in your hot wallet becomes large, you can transfer a large chunk of it to a cold storage without putting your refrigeration at risk by connecting to the network. The next time the refrigeration connection is made, it will be able to receive information about these transfers from the block link, and then the cold storage will be able to use the coins to do what is needed.
