All the right information that they need to know about bitcoin, and how to go about it are already discussed in this thread. I don't think there is nothing more that we can do for those newbies that are coming into bitcoin investment now, other than encourage them to go through the thread and ask questions where they are confused. A lot of people have shared their vast knowledge about bitcoin and their experiences here, so it is left for the newbies to show some level of commitment, by going through the thread and get whatever information they want.
You should understand that this thread is voluminous for newbies to go through before they can ask questions about what they need to know about bitcoin investment. There's always room for newbies to ask repeated questions on what they want to understand and when they seek for more clarity. Besides there are times when a newbie or any other person will come across an explanation about something they want to know but might not be satisfied with the response they got from a particular user, which will make them want a more broader and clearer understanding from some other users. Newbies are always eager to learn and know their way around so you can't completely blame them because if you reflect at when you were a newbie and came across this thread, you may find out you did similar things but all are just within the newbie era. However, everyone is open to discussions in this thread irrespective of being a beginner or not.
Even if the thread is voluminous, they can go through some pages, I'm sure they will get something out of it. The point is that someone who is eager to learn has to show some prove of work. Look even in college when a lecturer sell you his text book, you have to read through the book no matter how voluminous the book is if you want to pass your exams. If the secret of what you are looking for is hidden in the book, you have to find time to go through it.
Using how voluminous it is as an excuse will only show that you are a lazy individual who wants everything to be dished out to you on you table without making any efforts. I'm not saying that the newbie must go through the entire thread before asking a question, but going through 50 to 100 pages backward will help than not going through it at all. You don't really know what I did when I was a newbie, so don't assume what you don't know.
When I was a newbie and came across this thread, I read through the thread 150 pages backward from where I met it, that was how I got more insight about what the thread was all about. Everyone must not do exactly as I did, but going through some pages won't do them any harm. This way they will be more informed, thereby prompting them to ask more meaningful and constructive questions rather than jumping in and asking silly questions.
