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.
Investing in bitcoin does not mean you must have adequate knowledge before you start accumulating it. Once you have the basic knowledge about bitcoin and also understand that bitcoin is not a get-rich-soon scheme, you are good to start your bitcoin journey because bitcoin doesn't require much knowledge to hold it for the long term. Before you start your bitcoin accumulation journey, make sure you have a source of income that will enable you to keep an emergency fund that you will use to settle your financial needs, so that you will not depend on bitcoin investments to settle them.
