I am doing some additional research about Bitcoin, and I come across the link that talks many things about Bitcoin investment and launch. So I try to share with my fellow BitcoinTalk members, who have not gotten a full explanation about it before since they launched it in 2009. They will have more experience and knowledge about Bitcoin. And some newbie will like to be repeating questions about Bitcoin since they don't have an idea about it. So I see this will give them more explanation about Bitcoin and give them motivation to invest in Bitcoin for the long term.
