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.
Most people gain their financial knowledge from the internet because it is the best place to interact with different people all over the world, your advice should be that a newbie should not only be convinced by what they learn from a single entity who claim they are knowledgeable enough to teach or give an insight about the basic knowledge needed for their investment in bitcoin. A newbie should sort ideas from different investors then he should be able to access all the points and find out the best knowledge he will apply. We are already in digital era, gone are those days when you will need to meet people facially for them to explain some certain things you want to know about investment. Take a look at the forum, is it not the internet? But we have so many individuals who are well experienced about bitcoin investment here so it's about getting the right knowledge from the internet.
