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?
I have not invited anyone here because I think before you can invite anyone, there should be a sign of motivation and it should not be money, when money comes before passion, they don't go far. They will frustrate you on basic things they need to learn on their own, they might even struggle to even for merit because they don't understand anything not to talk of even communicating very well in the Forum. Just note that joining the forum doesn't make one a better investor.
If you want to introduce someone to forum, my best recommendations is to place them in the local board, they can easily get corrected over little things and when they get better, general board will not be hard to navigate around.
