My concern it how are we valuating Bitcoins? Will the valuation be based on US dollars just like now? Or will Bitcoins have a value of its own as a cryptocurrency that is decentralized, secure and a fast way of paying for services and goods. My concern is that we are really not trying to get separated from fiat currencies, and transform our world to one that is based on cryptocurrencies. All I see is that people using the idea of cryptocurrencies to accumulate more and more fiat currencies.
