Bitcoin wallet is divided into cold wallet and hot wallet
Generally speaking, blockchain wallet is used to store digital currency. In fact, blockchain wallet does not store digital currency, but a tool to store key (private key and public key). With the key, you can have the right to control the digital currency in the corresponding address, and use the digital currency collection address generated in blockchain wallet, You can accept the digital currency transferred to you by others, and you can also transfer the digital currency you own to others.
classification of digital currency wallets:
can be roughly divided into two categories, hot wallet (online wallet) and cold wallet (offline wallet)
first, hot wallet
Hot wallet is also called online wallet, It includes light wallets and heavy wallets (all node wallets). The wallets that need to be connected to the Internet can be directly traded
1. Light Wallet:
does not store the complete blockchain, only stores the data related to itself. It is small in size and can run on mobile phones, computers, web pages, etc
advantages and disadvantages: it does not occupy memory, supports a variety of digital assets, has a good user experience, is fast for novices, but transaction verification is a little slow
2. HEAVY WALLET (full node wallet)
maintains all blockchain data, completely decentralizes and synchronizes all data. It has better privacy and can verify the validity of transaction data locally
advantages and disadvantages: it has better privacy and faster verification of information, but it needs to synchronize data before each use, takes up a lot of hard disk space, and does not support multiple digital currency transactions
Second, cold wallet
cold wallet is not connected to the Internet, also known as offline wallet; For example, professional hardware devices, or private keys (mnemonics) written on paper
1. Hardware wallet
Hardware wallet is to store digital currency with professional hardware, store the private key of digital assets in a chip, isolate it from the Internet, and plug and play
2. Paper wallet
the advantages and disadvantages of writing the private key on paper and then deleting
cold Wallet:
is relatively safe, but it is very troublesome to create a wallet and trade. It is difficult for novices to operate, and the price of wallets is relatively expensive, generally ranging from thousands to tens of thousands of yuan. If you don't have a large amount of digital assets, you don't need to consider
generally, it's recommended for novices to use light wallet. Light wallet is easy to operate and easy to use. Personal used geekwallet

bitcoin wallet can be divided into cold wallet and hot wallet according to the storage method of private key
01. A cold wallet is a wallet that can't access your private key on the Internet
cold wallets often rely on "cold" devices to ensure the security of bitcoin's private key, such as computers that are not connected to the Internet, mobile phones, small notebooks with private key addresses, etc. Cold wallet avoids the risk of hackers stealing the private key, but may face physical security risks, such as computer loss and damage
02. Hot wallet refers to the wallet that can access your private key on the Internet
Hot wallets are often in the form of online wallets. When using hot money package, it is better to set different passwords on different platforms and open secondary authentication to ensure the security of your assets
wallet is actually "a management tool for private key, address and blockchain data".

transactions in bitcoin are completely anonymous. That is to say, no one knows how much money you have and where your wallet is
so even if people want to steal you, they don't know where to put their hands.
When it comes to cold wallets, I think this knowledge is relatively deep, and the latest procts have always been concerned. According to the more authoritative answer of the network, it is like this:
< blockquote >cold wallets refer to bitcoin storage technology developed by information technology companies that provide blockchain digital asset security storage solutions. Cold wallet integrates the functions of digital currency storage, multiple transaction password setting, publishing the latest market and information, providing hard fork solutions, etc., and uses two-dimensional code communication to make the private key never touch the network, which can effectively prevent hackers from stealing
< / blockquote >hardware cold wallet has great advantages
< blockquote >the storage function of hardware cold wallet is similar to that of hard disk, but it needs to pay password when trading, and randomly generate strong seed password to obtain private key and address, and each transaction is digitally signed and commented, which can be checked at any time; The online app can query the latest market and information online, open and transparent information, automatically detect the transaction confirmation, and never touch the private key
< / blockquote > cold wallet
Hardware Wallet: it is a special electronic device used to store encrypted assets. Its function is to store the private key in the internal chip. The private key will never leave the device, so it is very safe
cold Wallet: it means that the private key will never touch the network, and the private key will never enter the network.
