If the goal of the beginners was only to invest in Bitcoin, I think there would not be so much time that the beginners would need to spend to increase their knowledge. Unless these beginners are people who really don't know about Bitcoin or how to buy Bitcoin in the market, it is clear that they still need more time to learn. But if it's just for investment, they only need a few things that they have to learn and these include how to buy Bitcoin on a well-known exchange and how to store it in a wallet that is considered safe by many people. Apart from that, they only need knowledge about Bitcoin and knowledge about how to see better market moments in order to increase their enthusiasm in investing in Bitcoin.
