A Review on Bitcoin wallets

Bitcoin transactions are not reversible. We can neither send it nor receive it without having any access to both public and private keys. A Bitcoin wallet lets us transact our resources and also keeps our keys secure. As we cannot rely on the inbuilt Bitcoin security system, we need to implement a multi-step security system for ourselves.

Types of Bitcoin Wallets

There are various types of Bitcoin wallet, starting from

  • Online/Software wallets
  • Paper wallets
  • Hardware wallets, etc.

An active connection to internet is the only requirement to access all your online wallets. And the physical electronic devices, which secure your bitcoins are known as hardware wallets. The online/software wallets can be easily downloaded to your operating device, such as cell phone or tabs or etc. While, the paper wallets can be used offline. They are the Bitcoin private keys printed in a paper.
