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.
Basic understanding is enough to start your bitcoin hodl journey since you will not care about the prices especially if you do DCA since your main concern is your accumulation and not those unnecessary things that can bother your focus.
But you can continue to learn while on process of accumulation since its important to start since if you wait for long time to learn a lot of things then provably that you will just face some delays since provably you will doubt to start especially if you see the market is dumping. I understand your point, but if you are at the point that you are sure to invest with bitcoin and already know that this is good asset then start to invest. You will only loss a lot of money if you trade it , but if you are buying and hodl it for sure the risk is so low since your money is just there waiting for the timeline you set to sell it.
