Value follows belief, yes, and confidence. Bitcoin's value is based on hubris - excessive confidence - and this will fade. I believe in the value of digital currency and smart contracts, absolutely. The application for blockchain technology has only just begun. The reason for Bitcoin's continued lustre is its recognition and acceptance and its ability to be traded for ICO tokens. The value of Bitcoins is controlled, ultimately, by the exchanges. The more coins they accept as legitimate two-way trading coins - in and out of ICOs - the quicker will be the demise of Bitcoin. When it becomes possible to trade gold tokens, backed by real gold in a vault for which a person owns a certificate, in exchange for ICOs, then it's hasta la vista, BTC. Gold has recognised intrinsic value, application - an immutable substance useful not just for jewellery but also as a conductor - and a long time, universally recognised and accepted, store of value.
