it depends on your country there is an app on your country that is engaged on bitcoin that lets you buy and sell fast and easy.
Before owning any bitcoin, you need somewhere to store them. That place is called a "wallet." Rather than actually holding your bitcoin, it holds the private key that allows you to access your bitcoin address (which is also your public key). If the wallet software is well designed, it will look as if your bitcoins are actually there, which makes using bitcoin more convenient and intuitive.
Actually, a wallet usually holds several private keys, and many bitcoin investors have several wallets.
Wallets can either live on your computer and/or mobile device, on a physical storage gadget, or even on a piece of paper. Here we'll briefly look at the different types.
Electronic wallets
Software wallet
Online wallet
Mobile wallets
Hardware wallets
Paper wallets
Are bitcoin wallets safe?
That depends on the version and format you have chosen, and how you use them.
The safest option is a hardware wallet which you keep offline, in a secure place. That way there is no risk that your account can be hacked, your keys stolen and your bitcoin whisked away. But, if you lose the wallet, your bitcoin are gone, unless you have created a clone and/or kept reliable backups of the keys.
