That is the wrong perception. There are many people who are not aware of bitcoin till now. I understand that people find it hard to believe but one day they will regret that they did not follow our advise.
If everyone in the world buy some portion of bitcoin, you can't image how valuable bitcoin can be.
I know that you do not have any ill intentions regarding your post but let me tell you now that people will not heed your advice no matter, they have their own minds to decide what to do and I think that you should understand. There will be people who will agree with you that's for sure but do not drill in your ideals to other, let it seep in. And if the time comes that you are right then it is their fault not yours. I did what you said a long time ago and I think it is a good way to have a secure albeit uncertain future. Let the people regret their decisions OP.
