By the way, Facebook was founded in 2004, it didn't even have positive cash flow until 2009 (5 years later!). As of January 2014 they still had ONLY 1.2 billion active users (10 years later!)
Facebook was
launched to the public Sept. 2006. Bitcoin also had a period before its Jan 2009 launch wherein it was tested by a smaller group. So thus Facebook is only 8 years old as a public service and has 1.2 billion users. Bitcoin is nearing 6 years old as a public service has about about 1000X less users. Sorry there is no comparison.
