How do I feel that BG's skills are not up to par? I opened an account in BG in front of my family seal. To be honest, the front-end added animation rendering, which looked very smooth, but soon realized that the technology was not up to par. Firstly, there is the recommendation code. Surprisingly, the case of the recommendation code is sensitive. Either you use pure numbers or the case of letters is not sensitive. This small problem cannot be solved, which shows that the backend is not working; In addition, users who have used recommendation codes cannot view or operate them on their mobile devices. They can only log in to the web, and the logic is quite confusing. This is either due to insufficient backend manpower or backend stubbornness! And what is astonishing is that the double leverage of the currency standard opened short, and there was an explosive price. Obviously, this is not just a problem with backend technology, but also because the product manager has never made a contract. In this VOXEL/USDT incident, the bug has existed for such a long time, and the risk control service did not notice it. The rollback and rolling back were chaotic, indicating that the backend is quite messy. It is not surprising that these problems have occurred.
