I think bitcoin information is a continuous process but the major one to start with is the basic knowledge and understanding of bitcoin, before a beginner invest in bitcoin he should know what he want and how to get it, there are many strategy for different investors it all depends on the category such investor falls into, there are newbies that has sufficient amount both for investment and emergency funds, I think this people should also know that bitcoin is not a short term investment so that their expectations won't be cut off.
The concept or principle of Bitcoin investment doesn't state that everyone most have enough or sufficient knowledge before they could start investing on Bitcoin because in times of Bitcoin investment there is no fundamental analysis you should know before investing, perhaps that's one of the good things about Bitcoin investment because unlike most investment were you will need to have a very good knowledge about it before starting but however in times of Bitcoin you don't need much of that because you can start investing even when you don't no much about it and the strategy to use, however the introduction of DCA method became a game changer for so many persons who are looking for a strategy and also those that feels that there accumulation budget is too small for them to start the Bitcoin journey can now invest through DCA strategy with the believe that they will surely get to there destination in Bitcoin in the future.
One thing about Bitcoin is no matter how knowledgeable we think we are, can never be sufficient through out our Bitcoin journey, the more we keeping using and accumulating Bitcoin with time the better we grow further in understanding much more about Bitcoin.
Secifically down to Bitcoin investment the DCA approach is considerate enough for everyone, with no need for any further analysis and perfect timing, since the strategy is accumulating Bitcoin at specific regular intervals without considering the current price. The DCA appproach is just about keep buying and adding to one's portfolio without monitoring the value whether a DIP or pump.
