Sometimes spending a little money to follow the actions of certain top accounts, what do you end up discovering? Actually, most so-called "big V" accounts are only at this level, and some are even less thoughtful than you imagine. By the time you realize it, that tuition fee will have been paid. Anyway, since you have to pay tuition in this market, instead of blindly FOMO, it's better to figure out early who really has something and who is just good at talking. Ultimately, whether the money is worth it or not sometimes has little to do with the numbers.
