This are the few I have learned and I am looking forward to increase my findings about bitcointalk and everything behind bitcoin, one day I will look back and smile at my Genesis.
One interesting characteristic of this forum is that no one will charge you any money to teach you anything you want about Bitcoin, cryptocurrency, or general life knowledge. I view the forum as a free school where I can come with any Crypto-related questions and get answers; this is the best form I have ever seen.
