A huge sum of money that was lost but recovered, thanks to Binance, thanks to Sisi, reviewed the three major wind control mechanisms to ensure that the big money is not mistaken In the morning, a BTC transaction was not converted to WBTC and was directly referred to the ETH chain. After withdrawing it, I immediately realized that there was an error and was surprised. I immediately contacted the customer service of the APP and found that I couldn't find a human customer service representative for a while. Then I immediately called Sisi, and she immediately helped me get in touch. In that moment, her response was like that of a "Binance Angel", and she immediately contacted her colleagues to inquire and intercept. At the same time, the backend system also showed a rejection, finally avoiding danger. This incident reflects Firstly, Binance's response is really fast. I replied within 30 seconds after sending the message. Thank you again @ sisbinance. After all, it may have been woken up by me early in the morning. I am truly touched and sorry, and I don't know how to reciprocate. SISI said she spends most of her time online and is still coughing. In fact, over the years, whether it's @ heyibintance or the Qianjiang Yue I've contacted before, it feels really easy to find someone on Binance. Even countless retail investors can @ Yijie anytime in various groups. It's actually quite difficult to think about, just like when I use Futu to trade stocks, if you encounter problems, you can always @ the boss or find core personnel to talk about something. It's really not easy. In the past, some people even turned against Tian Gang, saying that this did not prove good and should be institutionalized. However, in fact, this has nothing to do with the quality of institutionalization, but rather a supplement to the already good foundation of institutionalization. Secondly, the construction of risk control mechanisms in the exchange's backend is crucial. For example, if you transfer SOL to a PUMP contract address, BTC to a non BTC chain, or ETH to a non ERC20 address, I hope they can all be rejected. My last large sum of money was transferred from SOL to the contract address, not from Binance, and it has been lost forever. My impression of Binance actually originated around 2018, when I made a deposit error and Binance helped me retrieve it. It was a pleasant surprise for small investors and small retail investors at that time. Thirdly, when withdrawing large funds, it is necessary to add a risk control to oneself In the future, I will add a risk control to myself, divided into three parts. 1. In terms of time, one should not rush and should be calm and composed. For example, give 1 minute to operate slowly and do not do anything else at this time. 2. In terms of mechanism, it is divided into two transactions. First, make a small withdrawal, and then make a large withdrawal. Most of the time, it seems completely unnecessary, just like the address I have verified today, and it is often made in this way, but it is an error! In the future, it is necessary to wait until the first transaction arrives before operating. This also conforms to the first rule, so be calm and not in a hurry. 3. When checking, it is necessary to verify the chain and address, and it is best to check the address letter by letter. If you do these slow movements a little more, there won't be tragedy. The tuition fee I paid for this is huge.
