Bitcoin, unlike most traditional currencies, is a cryptocurrency. Thus, the approach to this type of currency is completely different, especially as regards its acquisition and storage. Since bitcoins do not exist in any physical form, they can not technically be stored anywhere. Rather, they are the private keys used to access your public Bitcoin address and sign for transactions that must be securely stored. A combination of the recipient’s public key and your private key is what makes a Bitcoin transaction possible. There are different forms of Bitcoin portfolios that meet different requirements and vary in terms of security and safety, convenience, accessibility, and so on.
