Aren’t bitcoin holders actually providing value by investing their hard worked fiat money in to bitcoin? As a matter of fact you might be called a free rider, but at the same time your invested money is doing all the work for you. At the end we all contribute, whether it’s just by investing or actuall work on difrent projects such as ICO’s. I’ve never had Facebook account, but it doesn’t mean I don’t contribute to Facebook, which is killing me by knowing I probably do.
