It's great that you are spreading the word about Bitcoin. Good Job, OP. If I was on your place, I would just explain the basic principles and the core concept of Bitcoin and blockchain technology. I wouldn't tell the noobs when to buy and when to sell. Nobody can predict the market, even the best crypto traders are failing sometimes. Knowing Bitcoin is one thing, learning and practicing crypto trading is a different thing.
By the way, I don't think that the main reason for the small price growth from 16K to 23K is the Chinese New Year. Wasn't Bitcoin banned in China?
The best advice you can give is that Bitcoin is an investment that is most successful with a target of 4 years. It is economically designed this way. No one has ever failed when hodl'ing for more than 4 years, the charts prove it!
According to this article, Bitcoin has been banned by China on 3 occasions. I remember reading another article around the time of the last China ban that the count was in excess of 7 occasions. Yet, many Chinese exchanges and services still operate today. So this tells you how effective these so-called bans really are.
Bitcoin Cannot Be Banned!
