I would love us to share this idea, I have it in mind to introduce Bitcointalk to the people around me, but I wish to ask, how do I go about it,
Just give them a brief description about Bitcoin and emphasize its main feature then leave the rest for them to research for themselves. Spoon feeding them with a lot of info that available on the internet will just gonna make them more reliable to you rather than understand the technology by themselves.
Do you think it will be of advantage or disadvantage to my community?
It depends on what kind of community you have. Its an advantage if you have an open minded community that willing to learn and disadvantage if the community youve got is very toxic. You will just be subjected to criticism and blaming once they lose money through Bitcoin even though you gave them a disclaimer. Choice is yours since you can freely enjoy Bitcoin investment without the need to disturb your personal life.
