In order for btc to become the main store of value, majority of the population must agree on that it will be so, since btc does not have any intrinsic value; the value of btc is decided purely by demand for btc.
So, my answer is no. Btc is not the future of our economy.
Nothing has an intrinsic value, fiat only has value because the governments of the world say it does, but what it is going to happen when the people stop trusting the words of their governments? Fiat will lose all its value, bitcoin at least is a new technology with the blockchain backing it, so the bitcoin network has some value, it is impossible to know how high is that value but we try to discover that every day in the market of cryptocurrencies.
