I've made a lot of money with Bitcoin. Not because I'd ever thought it would amount to anything, but I was sitting on a lot of them, then all of a sudden they went from being worth next to nothing to $1600 a pop. I sold most over a period of time. They were literally giving away 10,000 bitcoins to anyone who wanted them when they first came out.
I wish I had taken as much as I can when they were giving them away and nobody wanted them. I'd be worth hundreds of millions now.
It's safe to say BTC is here to stay, even if the feds ban it. It's the preferred currency of the black market and deep web.
