Pros & Cons
Software wallets are convenient since they give immediate access to your ada, however, like all software they can be susceptible to risks such as hacking and malware. On the other hand, paper wallets and hardware wallets are less convenient but generally regarded as safer in terms of managing your ada.
Daedalus is a full node wallet, developed by IOHK, which will allow you to store ada, the native cryptocurrency of the Cardano blockchain.
