Introduction
Cryptocurrencies have surged in popularity since Bitcoin’s inception in 2009. While no storage method is 100% secure, adopting the right strategies can significantly enhance the safety of your Bitcoin and other digital assets.
Bitcoin Storage Fundamentals
Bitcoin transactions involve two cryptographic keys:
- Public Key: Used to create wallet addresses and encrypt transactions.
- Private Key: Grants access to your funds; must be kept secure.
Ownership is recorded on the blockchain, but wallet security depends on how you manage your private keys.
