How to setup your Bitcoin cold storage for free

What is a Bitcoin wallet ?

Bitcoin cold storage is the practice of storing Bitcoin holdings in a secure offline wallet. This method of storage is commonly used by long-term savers who want to keep their Bitcoin safe. The best cold storage devices are hardware wallets, but they can be pretty pricey for Africans to get their hands on. The most affordable way to store your Bitcoin offline is by using software wallets or generating paper wallets offline.

Paper Wallet

Paper wallets are a form of cold storage where Bitcoin private keys are printed or copied on paper, which oftentimes also includes the wallet address. Paper wallets enable you to store your Bitcoin safely offline. This makes paper wallets significantly more secure compared to hot wallets, which are accessible online and vulnerable to hacking and theft.
Creating a paper wallet is a simple and inexpensive way to store your Bitcoin offline and keep them safe.
There are many paper wallet generators available online, but not all of them are trustworthy. It’s important to choose a reputable one that has been around for a while and has a good reputation in the Bitcoin community. Some popular paper wallet generators include:
