It's not very difficult to get basic details of Bitcoin as they are readily available on internet. If one has acquired basic understanding of Bitcoin then their is no harm in getting started with small amount. Because in the start we all do mistakes that results in monetary loss and these mistakes helps us in understanding how to invest in Bitcoin. As a newbie if we get ourselves familiar with DCA then we can save us from initial mistakes and monetary loses. The only thing difficult is getting started and getting on the track, after that it's a smooth sailing.
A beginner should not rely on the internet (social platforms) to gain basic knowledge about Bitcoin. I would rather suggest that instead of using the internet, one should become a trusted person and depend on him to gain basic knowledge about Bitcoin. Because, finding the right source from the internet is not an easy task for a beginner or a newbie. Rather, he will not be able to gain proper knowledge about Bitcoin by collecting or reading information from wrong sources. Because they do not have the verification capability. So I would completely discourage relying on the internet for basic knowledge. Try to find a skilled Bitcoin investor and ask him.
