Yeah, that's what I am saying about basic knowledge. Understanding that Bitcoin is moving quickly and prices vary from time to time.
It's true that they can buy and just understand it later. But in general speaking about investing, someone shouldn't get into an investment that they don't totally understand even the basics of it.
The first investment in any investment is to invest in learning to have a better understanding. When there is no knowledge about a particular investment it means you are investing in nothing, it doesn't even matter if what you are using to invest is much. When their is no knowledge in an investment it is possible to be at last which the investment won't be even productive. Knowledge carries the information one is suppose to know concerning an investment and if the knowledge is not there it means one knows nothing.
