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.
"launched to public" in 2006? Bitcoin is just known to part of the public during the 2013 run up, does that make it a little over 1 year old? Or do we start with inception dates?
Even if we use your numbers with facebook taking 8 years to get 1.2 billion users, for such an EASY technology to use....expect bitcoin to take much longer...but that is Okay, I'm patient

"Sorry there is no comparison" -- Every part of your (and my) argument is a comparison ....are you just trying to troll?
