Common quote from Robin Jones Gunn, you may or may not have heard about it, but is "You go alone, you go fast, you go with people, you go far". Have you met anyone who knows about bitcoins, and then you tried to introduce them to this forum to come join this community, but they refused? I like to see what maybe their reasons where.
I am just over relating that quote to bitcoins; do you have the opinion that lone investors who are not members of any kind of forum or community about bitcoins or cryptocurrency can still be very successful investors?
Let me speak about my own experience, I would never have known anything about Bitcoin without the forum. The forum served as a foundation for my Bitcoin adventure. So I would say that you might need a forum like this to give you all the critical information that will help you understand Bitcoin. After you have gotten most of the information, you need to start making personal decisions and not depending on the group. With the level of information you have acquired, one can now make individual decisions.
But there are still many people that are not members of any forum but they are well-grounded in Bitcoin Investment. They get information from diverse material online and offline and they manage to get the right information.
