A new beginner don't need any understanding about the market because his focus is only on buying bitcoin overtime without selling. It is hard to predict the dip no matter the knowledge that you have in the market.
They still need to understand the market before investing.
Someone who's investing without basic knowledge is going to have emotional hiccups and might panic in the end. That's why if there are beginners there, I still advise them to at least learn and understand what volatility is before buying Bitcoin.
It's hard to buy something that you don't understand even if the crowd says that it's fine.
