It was written that way but look what they did to their bitcoins, have they spent it? NO. Are they spending it? NO. bitcoin created a whole new class of an investment, though it was designed to be a medium of a transaction, people have taken the decentralization as a game for these coin's capability of rising and declining prices. We always say that bitcoin is an alternative currency, yet we don't use it as an alternative, maybe for some they do but most of us? hell no. We are afraid of the volatility, that's the truth.
