Arbitrage has been going on for a long time I understand why the Northwest 985=Beijing Shanghai Double Non Aligned Movement The reason is that the two are almost equivalent, and the fluctuation may not exceed 20% It's like Cetus on SUI giving you an annualized rate of 15%, while ETH Uni only gives you an annualized rate of 10%. It's not that SUI has an information gap, it's that it could really be hacked. (Done, using Crypto primitives again here) Besides, I think where your hometown is is also very important. The balance of Jiangsu, Zhejiang, and Anhui is tilted towards Shanghai. If your home is in the northwest, then you can go to Lanzhou University. If we rewind 30 years ago, I think there may still be a significant information gap, but now the information gap is getting smaller and smaller. Of course, the proposal of living abroad is too difficult ... identified as a category of whimsical ideas.
