Q3: Centralized wallet? Decentralized wallet? Why can’t centralized wallets query transfers?
To give an example: your own wallet address is A, and you transfer 10 USDT to address E, but if you use the transaction hash value to query, you can only query a random ledger address B (or C or D, etc.) of the service provider. etc.) transfer with E.
In the same way, E cannot know whether the 10 USDT were transferred out by you, because E can only see that the ledger address B transferred 10 USDT to him. This is why centralized wallets cannot query the real transfer information on the blockchain.

Q4:Why do I win or not win consecutively?
First of all, not winning multiple times in a row is a small probability event. Secondly, winning or not winning is a random event. The frequency of random events will tend to a stable value.
In the case of non-iteration, the probability of things appearing is equal to everyone. In this case, everyone is fair.
At the same time, random events will follow the law of large numbers (under the same conditions of the experiment, repeat the experiment many times, the frequency of random events is close to its probability definition of the law of large numbers). When the frequency of transfers continues to increase, winning or not winning the prize will The probability will tend to a stable value.
So please continue to transfer money. As the frequency of transfers increases, the total probability of winning will increase.

Q5: Why is the payment delayed?
In order to ensure the security of funds, blockchain technology will perform multiple calculations, comparisons, and confirmations. So the calculation speed is slower, but the most important thing is safety.
