Understanding Crypto Airdrop: Transparency in Cryptocurrency Wallets

After a preliminary understanding of cryptocurrency wallets, I found that the amount of money in each wallet is public. In the existing financial system, we need to provide our account number to the other party whenever we want to use an account. Only with an account number can the other party know where to make a payment and which account made the payment at what time. Digital currencies are no exception. In the blockchain digital currency system, a wallet address is equivalent to a bank account number. When receiving payments, you need to provide a wallet address to the payer. After receiving the payment, you can also see a transaction record showing which wallet address transferred funds to your wallet. Once we know any wallet address, we can use the “import wallet” feature in our wallet software and enter the wallet address to “observe” that wallet, seeing how much money (balance) it contains.

As long as we know the other party's wallet address (account number), we can clearly understand how much money is in that wallet. It’s similar to how knowing a bank card number allows us to see how much money is in that bank card. Is this reasonable? It seems so; each cryptocurrency is stored on the blockchain network, and theoretically, everyone can trace its origins and transaction history, which is transparent and open. Isn't this precisely the source of confidence for some people in the cryptocurrency system?
