I think a beginner can start with the basic knowledge, as they can not be able to get all the required knowledge without investing. However, When a beginner is provided with the basic knowledge about bitcoin investment it means that they're fully aware of the market volatility, and also knowing that investing with our pocket money is not advised but from their discretionary fund, and also knowing that emergency fund is required during this process of accumulation, and also, the risk that is involved and how to manage them. As Long as a beginner is provided with this guidelines and it happens that their discretionary fund is available, they can start accumulating bitcoin as soon as possible, probably if there's any information that they're missing out I believe with time they will be able to figure it out.
Basic knowledge is not enough to start investing, you need to have a source of discretionary income and mental preparation. Suppose you have basic knowledge but do not have a source of discretionary income, then can you start investing and sustain it for a long time? No, it is not possible. Because you may be forced to withdraw that money from the investment and face losses. Even if you are not mentally prepared, there may be errors in your plan and doubts may arise in your mind about the investment.
Basic knowledge is enough for investment in terms of knowledge, but overall basic knowledge is not enough to start investing.You don't have to get yourself confused it the same you are saying basic knowledge is basic knowledge and it seems that you both are in the same spotlight of saying certain vitals about basic knowledge.
