1. There are many kinds of wallets in the market, which can be divided into desktop wallets, mobile wallets, online wallets, hardware wallets and paper wallets according to the platform; According to whether it is connected to the network, it can be divided into cold wallet and hot wallet; According to the degree of autonomy and the way of interaction with the network, it can be divided into full node wallet, SPV light wallet and third-party wallet
for blockchain wallets, you can see the evaluation of wallets in password finance if you go to the tutorial.
2. In order to understand the blockchain wallet, we must first understand several core concepts
1. Wallet address: similar to the bank card number, a person can have multiple bank cards. Similarly, he can also have multiple wallet addresses. A wallet address can only correspond to one private key
2. Wallet ID: customer ID (name) similar to bank card
3. Public key and private key: the holder of the private key is the holder of the currency in the bank card. The private key can calculate the public key, the public key can generate the wallet address through a series of digital signatures, and the data encrypted by the private key can be decrypted by the public key, or vice versa
I know this area quite well, and I have some ideas to develop a blockchain wallet. After all, it is a high-tech wallet. Before I learned about a development company called Xuanling technology on the Internet, and also consulted the people over there. I felt that it was quite professional. I hope I can help you~

Drawing method:
connect two or more relative low points into a straight line to get support line
connect two or more relative high points into a straight line to get pressure line
usage:
1. The function of support line and pressure line
support line is also called resistance line. When the stock price falls near a certain price, the stock price will stop falling and may even rise. The price that prevents the stock price from continuing to fall or temporarily prevents the stock price from continuing to fall is the position of the support line
pressure line is also called resistance line. When the stock price rises to a certain price, the stock price will stop rising, or even fall back. The price that prevents or temporarily prevents the stock price from rising is where the pressure line is

The function of support line and pressure line is to prevent or temporarily prevent the stock price from moving in one direction. At the same time, the support line and pressure line have the possibility of completely preventing the stock price from changing in the original direction
2. Support line and pressure line transform each other
If a support line is broken, it will become a pressure line; Similarly, if a pressure line is broken, it will become a support line. This shows that the position of support line and pressure line is not unchangeable, but can be changed, provided that it is broken through by effective and strong enough stock price changes< Generally speaking, the importance of a support line or pressure line to the current impact has three aspects: one is the length of time the stock price stays in this area; the other is the length of time the stock price stays in this area; Second, the trading volume of stock price in this area; The third is the distance between the occurrence time of this support area or pressure area and the current period

The price fluctuates greatly. Due to the intervention of a large number of speculators, the price of bitcoin for cash fluctuates like a roller coaster. Making bitcoin more suitable for speculation rather than anonymous trading

the concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. According to the idea of Nakamoto, the open source software is designed and released, and the P2P network on it is constructed. Bitcoin is a virtual encrypted digital currency in the form of P2P. Point to point transmission means a decentralized payment system

unlike all currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses the distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses the design of cryptography to ensure the security of all aspects of currency circulation

the decentralized feature and algorithm of P2P can ensure that it is impossible to artificially control the value of bitcoin by mass manufacturing. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity
