This thing came up to my mind suddenly. As I know a currency is a transaction medium that majority of the people agree to use to exchange their items with them. If it is the case, if majority refused to use crypto currencies, what will be the consequences may occur ? And how it will affect to the ICOs ? Any Ideas?
"a product that has no market, has no market value at all". If you are going to look at it, you can easily answer your question in the first place. If people rejects cryptocurrency, its market value will be trash and you can't even think about it be still good, but the opposite will happen, it will be thrown to the state of oblivion.
