1. To store cryptocurrency, you need a cryptocurrency wallet. Broadly speaking, a cryptocurrency wallet is a program that stores your private and public cryptographic keys, which you need to use to access the blockchain on your own behalf and to make transactions with your cryptocurrency. The public key is similar to the wallet address, while the private key is used to unlock the public key. When someone wants to send you money, the other party will reassign their address to you. To do this, the sender needs access to their private key. Then, to unlock and use the newly received money, you have to enter the private key that corresponds to your public key. Sometimes we need to confirm that a coin transfer to someone else has been successful, or if we want to find evidence to check the details of a wallet address, we can do so via the blockchain browser, where we can find out what transactions have been made to a wallet address, how much assets are in the account, etc. Cryptocurrencies are both public and hidden. Public means that all transactions are recorded on the blockchain and can be accessed by anyone, for example, if address A transfers coins to address B, everyone can see it. Concealment, on the other hand, says that although the records of transactions between different addresses can be seen, we do not know who exactly is behind the address, thus protecting the privacy and security of individuals. Mainstream cryptocurrencies such as BTC and ETH have their own blockchain browsers, and tokens based on Ether ERC20 are generally accessible using ETH's browser as well. So, the following is an example of a commonly used browser for Ether, etherscan.io. (1) You can see a lot of information on the home page of etherscan.io browser, such as the current market capitalization of ETH, block height, mining records, the latest transaction records, transaction volume analysis, and so on. There is a search engine bar in the top right corner of the page, where you can enter the address you want to search. Once you have entered the address and clicked search, you will be taken to the details page for that address. Here you can see what the current ETH balance is for that address and how much it is worth in USD. At the bottom of the page there is a table of the last 10 transactions for that address. The data in the table is very detailed, with the exact time of each transaction, whether it was transferred in or out, which address it was diverted to, the amount transferred and so on, all of which can be viewed. (2) If you want to see transfers based on Ether ERC20 tokens, you can click on the column labeled "Token Transfers" at the top left of the table, which shows the transaction information for that address, including the time of the transaction, the type of token, the address of both parties, the amount of the transaction, etc. This information includes the time of the transaction, the type of token, the address of both parties, the amount of the transaction, etc. The above is the general method of searching for the address of a wallet. The method of searching for the addresses of wallets of other currencies is similar.

2. The content introduced above is only about the basics of cryptocurrency, which is related to whether we can make money through cryptocurrency. Cryptocurrencies make money not only by scientific methods to increase income, but also by finding ways to save money. The handling fees are small, but they must not be ignored. I have calculated that with frequent transactions and long trading hours, the accumulation of fees can add up to more than 10,000 U a year. Next I will introduce a few common ways to reduce fees on large trading platforms. (1) Lowering Binance's fees Binance is currently the world's largest digital currency exchange, and you must sign up for Binance if you want to speculate on coins. The transaction fee is deducted from the assets received. For example, if you buy Ethereum/USDT, the fee is paid in Ethereum. If you sell Ethereum/USDT, the commission is paid in USDT. Example. You place an order for 10Ethereum at a price of USD3,452.55 per share. Transaction fee = 10Ethereum0.1% = 0.01Ethereum Or you place an order to sell 10Ethereum at 3,452.55 USDT per share. Transaction fee = (10Ethereum3,452.55USDT)*0.1% = 34.5255USDT What many people do not know is that the Binance transaction fee can also be reduced.

(2) Reducing OKX fees OKX is a professional digital currency trading platform loved by many users, and its transaction fees can be reduced. Depending on the volume of transactions, OKX divides its users into two levels: normal and professional. Ordinary users are graded according to their OKB positions, while professional users are graded according to their trading volume and asset size.

When calculating the fee levels, if the coin trading volume, total trading volume of delivery and perpetual contracts (USDT delivery contract, coin-based delivery contract, USDT perpetual contract, coin-based perpetual contract), option contract trading volume, and asset volume meet the conditions of different fee levels, users will enjoy the fee discount of the highest level.
