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.
