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.
It is not clear which investment strategy you are referring to in the post, everyone may use different strategies for investing. But if you regularly buy bitcoins through DCA to grow your investment, you may not need to have much investment experience. Buy Bitcoins regularly and ensure the security of the wallet in which the invested Bitcoins are kept. This is the initial knowledge you need to invest in the DCA method. This is why it is said that dollar cost averaging techniques can be used to start investing with little knowledge, and over time you will gain experience with regular bitcoin purchases. This has been discussed many times in many posts in this thread.
