As a new investor I don't think it requires much knowledge.
(Though the saying goes that knowledge is king)
But once you go to the market, you can learn all kinds of things by yourself.
Actually, am not ok with the statement because going into investment without having adequate knowledge is like starting a journey without a direction and can also be liking to someone that intend to start a business without business ideas. As a new investor I think having adequate and the right knowledge before you invest is a wise approach.
Waiting to go to the market and learn everything yourself is like a woman that is trying to go to the market to buy different items without making list of things to buy in order of their importance and check if her money is enough to buy everything in the list which may lead to mistake and not being organized. An investor that has the adequate knowledge before investing will be more organized and confidence compared to someone without adequate knowledge.
On the contrary @teamsherry is right because investment on Bitcoin doesn't require much knowledge before you can start investment, actually is quite unfortunate that you still believe that knowledge is a determining factor on your Bitcoin journey perhaps that's why most people are still reluctant of starting investment on Bitcoin because they believe that having too much knowledge on Bitcoin is what determined there success on Bitcoin, however I want to inform you that you don't need too much knowledge in other to start accumulating Bitcoin because Bitcoin is not like other investment that requires going for a training or researching before you could start investment, on the contrary Bitcoin investment is so simple that a beginner who doesn't really no much about Bitcoin can easily start accumulating because since the intention is buying and holding you don't need any technical analysis to determine your accumulation. However @JayJuanGee has also explained several times on his replies concerning the reason why we don't need too much knowledge before we can start accumulating Bitcoin.
Basic understanding is totally fine if they just want to acquire bitcoin and they don't need deep knowledge about this since acquiring bitcoin doesn't need to have technical aspects needed because you can buy at what figures you are comfortable doing it.
Technicalities is just for people who want to trade for short time period since they really need to dig up more information regarding on past movements of bitcoin so that they can buy at good position then sell when profit is there. Its repetitive cycle for them that's why they need to look for charts to know what possible action should be done next to it.
For holders I guess they can do that at their own pace since the only thing they need to do is to have funds to spend and target years on when they should sell or to know their intention on why they acquire bitcoin for long term hold.
