The most expensive is information, and the one with the least marginal cost is also information.

Different information in different people's hands can create different values.

For example, on the first day of the epidemic, I learned about the outbreak in Wuhan in a small group, so I started contacting a source for masks through a friend on social media, and then it was about collecting money first, and then transferring it to the orderer. On New Year's Day, my wife and I were both shipping with SF Express. Later, another friend told me not to deal with masks; he would sell me two tons of melt-blown fabric, and I could just sell it for five times the price. At that time I had no money, and later the melt-blown fabric seemed to have risen to over 40,000 per ton.

Brother Ming organized a training class, and higher made a DeFi course that sold for over 2 million, also turning information into money. This is similar to the airdrop course I sold before; it's all about selling one's own information and experience at a low cost. To this day, many people who bought the airdrop course still keep in touch with me.

The last Binance voting was the same; many people made hundreds of thousands in a day. Although I didn't make much money, I gained traffic and channels.
