Increasing public interest in Bitcoin cannot change Bitcoin as digital cash. Bitcoin is run based on the P2P network concept with the aim of creating a transaction system that is free from intervention by any central authority or monetary authority. The worst possibility might happen if Bitcoin is no longer P2P digital money, the price could drop to zero if the government can intervene in market efficiency, prices, supply and demand, volatility and profits. Bitcoin is freedom because it is a P2P system that operates without the need for intermediaries such as banks or financial institutions, Bitcoin will remain digital cash in the present and future.
