No. If you think that then you haven't done your research. Countries around the world such as Venezuela have experienced a 95% devaluation in their currency vs USD. Countries like this need something like BTC as a store of value. BTC has so much potential, we've seen nothing yet.
@Taner if you think no one has been working on BTC then you're completely wrong, it is constantly being worked on!
Countries like Venezuela are good examples why the world needs cryptocurrencies, there are many examples around the globe where currencies get massively devalued, mostly due to low interest rates and printing money to have liquidity in the market. These things work only in the short term and then at some point it collapses. You can see this happening with the turkish Lira too right now.
