bitcoin wallet
a wallet usually has multiple private keys, and many bitcoin investors also have multiple wallets. Wallets can be placed on computers and / or mobile devices, on physical storage devices, or even on paper
e-wallet - e-wallet can be downloaded software or hosted in the cloud. The former is just a format file that exists on your computer or device to facilitate transactions. Hosted (cloud based) wallets usually have a more user-friendly interface, but you will trust a third party with a private key
software Wallet - installing a wallet directly on your computer can provide you with the security of your control key. Most have relatively simple configurations and are free. The disadvantage is that they do require more maintenance in the form of backup. If your computer is stolen or damaged, and your private key is not stored elsewhere, you will lose bitcoin
Mobile Wallet - mobile wallet can be used as an application for smart phones, especially if you want to pay with bitcoin in the store or buy and sell on the road. All of the online wallets mentioned above and most of the desktop wallets have mobile versions, while others (such as Abra, airbitz and bread) are created with mobility in mind
Hardware wallets - hardware wallets are small devices that are sometimes connected to the network for bitcoin transactions. They are very secure because they are usually offline and therefore cannot be hacked. However, they may be stolen or lost along with bitcoin belonging to the stored private key. Some large investors keep their hardware wallets in secure locations, such as bank vaults. Trezor, keepkey and ledger and the case are obvious examples
paper wallets - perhaps the simplest of all wallets, these are all paper with the private key and public key of the bitcoin address printed on it. These wallets are ideal for long-term storage (obviously, away from fire and water) or as a gift of bitcoin, because they are not connected to the network, so they are more secure. However, they are more likely to be lost
with services like walletgenerator, you can easily create new addresses and print your wallet on the printer. Fold, seal, and you're done. Send some bitcoin to the address and store or distribute it safely
